How to Crochet the Perfect Amigurumi Ball or Sphere – in Any Size!
Welcome, aspiring amigurumi artists! Today, we’re going to embark on a delightful journey to create the foundational element of so many adorable stuffed toys: the perfect amigurumi ball or sphere. This isn’t about knitting or sewing; we’re going to achieve this wonderful, three-dimensional shape using the magic of paper folding, often referred to as origami. Once you’ve mastered this technique, you’ll unlock a world of possibilities for creating your own unique characters and decorations. Don’t worry if you’re new to origami; I’ll guide you through every step with patience and clarity.
Choosing Your Paper: The Foundation of Your Sphere
The paper you choose is crucial for the success and aesthetic of your origami sphere. For this project, you’ll want something that holds a crease well but is still flexible enough to form a smooth, rounded shape.
Type and Weight:
I generally recommend using standard origami paper. This paper is specifically designed for folding and usually has a good balance of strength and pliability. It’s typically made from kozo or other plant fibers, giving it a lovely texture. For beginners, a slightly thicker origami paper (around 70-80 gsm) can be easier to handle as it’s less likely to tear. If you can’t find origami paper, good quality printer paper (around 80-90 gsm) can also work, though it might feel a bit stiffer. Avoid cardstock or very thin tissue paper, as they won’t give you the desired results.
Size:
The size of your starting square will directly determine the size of your finished sphere. Standard origami paper comes in various sizes, with 15cm x 15cm (approximately 6 inches x 6 inches) being a very common and excellent size for your first few attempts. If you want a smaller sphere, you can cut down a larger square. For a larger sphere, you’ll need a larger starting square. Experimentation is key here!
Single or Double Sided:
For the classic amigurumi ball, I prefer using single-sided origami paper. This means one side is colored and the other is white. As we fold, we’ll strategically reveal both sides, creating a beautiful, almost quilted appearance on the finished sphere. If you use double-sided paper, your sphere will be uniformly colored, which is also lovely! The folding process remains the same.
The Base Folds: Building Blocks of the Sphere
Before we dive into the full sequence, let’s get familiar with a couple of fundamental folds that are essential for this project. Making these folds cleanly and accurately will make the rest of the process much smoother.
The first essential fold is the “valley fold.” This is where you bring one edge of the paper to meet another edge, creating a crease that sinks inwards, like a valley. The second is the “mountain fold.” This is the opposite of a valley fold, where the crease bulges outwards, like a mountain ridge. For most of this project, we’ll be making valley folds.
The Fold Sequence: Crafting Your Amigurumi Sphere
Now, let’s begin the folding process! Take your square piece of paper and place it on a flat surface with the colored side facing down (if using single-sided paper). We’ll refer to the corners as top, bottom, left, and right, and the edges as top edge, bottom edge, left edge, and right edge.
1. **First Diagonal Fold:** Take the bottom-left corner of the paper and bring it up to meet the top-right corner. Make a sharp crease along the fold. Then, unfold the paper. You should now have a diagonal crease running from the bottom-left to the top-right.
2. **Second Diagonal Fold:** Now, take the bottom-right corner of the paper and bring it up to meet the top-left corner. Make a sharp crease along this fold. Unfold the paper. You should now have two diagonal creases forming an “X” across your paper.
3. **Horizontal Fold:** Flip the paper over so the colored side is facing up. Take the bottom edge of the paper and bring it up to meet the top edge. Crease firmly along the center. Unfold. You should now have a horizontal crease running across the middle of your paper.
4. **Vertical Fold:** With the colored side still facing up, take the left edge of the paper and bring it over to meet the right edge. Crease firmly along the center. Unfold. You should now have a vertical crease running down the middle. Your paper now has four creases: two diagonals and one horizontal and one vertical.
5. **Forming the Waterbomb Base:** This is a crucial step that creates a pre-creased shape that will help us form the sphere. Hold the paper so that the colored side is facing up. Gently push the left and right sides inwards towards the center, along the vertical crease. As you do this, the top edge should naturally want to collapse downwards. Guide the top edge to meet the bottom edge. You should end up with a smaller, triangular shape with four flaps. This is called a “waterbomb base.” Ensure all the creases are sharp.
6. **Folding the Side Flaps (First Side):** Take one of the top flaps (on the right side) and fold its bottom edge to meet the center vertical crease. Crease firmly. Repeat this with the top flap on the left side – fold its bottom edge to meet the center vertical crease. Your shape should now look like a kite with two flaps pointing upwards.
7. **Folding Down the Top Triangle:** Take the top triangular point of the kite shape and fold it down, aligning its bottom edge with the bottom edge of the two flaps you just folded. Crease firmly.
8. **Flipping and Repeating:** Flip the entire model over to the other side. You will see a flat surface. Now, repeat steps 6 and 7 on this side. First, fold the bottom edge of the right flap to the center crease. Then, fold the bottom edge of the left flap to the center crease. Finally, fold the top triangle down, aligning its bottom edge with the bottom edges of the flaps.
9. **Tucking the Corners (First Side):** Now, look at the two flaps you folded in step 6 (on the first side). You’ll notice small triangular pockets at the bottom of these flaps. Take the right flap and carefully tuck its pointed end into the pocket of the left flap. You might need to gently lift the left flap to get the right flap inside. Once tucked, flatten the area.
10. **Tucking the Corners (Second Side):** Flip the model over. Repeat step 9 on this side, tucking the right flap into the pocket of the left flap.
11. **Inflating Your Sphere:** You should now have a shape that resembles a slightly deflated ball with two small openings at the top. Gently blow into one of these openings. As you blow, the paper will expand, and your sphere will take on its rounded, three-dimensional form! Continue blowing until it’s as firm as you like.
Common Pitfalls and How to Avoid Them
Even with clear instructions, there are a few places where beginners often stumble. Don’t get discouraged if your first attempt isn’t perfect; these are learning opportunities!
* **Messy Creases:** This is the most common issue. When I say “crease firmly,” I mean it! Use your fingernail or a bone folder (if you have one) to make your creases sharp and precise. This is especially important in steps 1 through 4. If your initial folds aren’t clean, the later steps, particularly forming the waterbomb base (step 5), will become significantly more difficult, and your finished sphere might look lopsided. *To avoid this: Take your time with each fold, align edges and corners perfectly before creasing, and run your fingernail along the fold line firmly.*
* **Difficulty with the Waterbomb Base (Step 5):** This step can feel a bit counter-intuitive at first. The key is to trust the creases you’ve already made. The diagonal creases are your guides. As you push the sides inwards, visualize the paper wanting to collapse along those diagonal lines. *To avoid this: Make sure your initial diagonal and horizontal/vertical creases are well-defined. Gently encourage the paper to collapse; don’t force it. Sometimes wiggling the sides slightly can help the top fold down smoothly.*
* **Tucking the Flaps (Steps 9 & 10):** This is where you lock your sphere together. If the tucking isn’t done neatly, your sphere might come apart easily, or the joins might be very visible. You need to ensure the flap goes fully into the pocket. *To avoid this: Don’t rush this step. Carefully separate the layers of the pocket flap just enough to guide the other flap’s point inside. Once tucked, gently flatten the area to secure the fold.*
Varying Your Amigurumi Sphere
The beauty of this origami technique is its versatility! You can easily change the look and feel of your spheres.
* **Size:** As mentioned, the size of your starting square dictates the size of your finished sphere. Experiment with different sized squares to create a range of spheres, from tiny decorative accents to larger display pieces.
* **Paper Pattern:** Beyond plain colors, explore patterned origami paper! You can find papers with whimsical designs, floral motifs, geometric patterns, or even textured finishes. This can add a lot of personality to your spheres. For a more unique look, consider using paper from old books or magazines (ensure the paper isn’t too thick or glossy).
* **Color:** Don’t be afraid to mix and match! You can use single-sided paper of different colors for each sphere, or even try folding two halves using different colored papers and then joining them (though this is a more advanced technique).
Ideas for Displaying or Gifting Your Finished Model
Your beautiful origami spheres are wonderful on their own, but they can also be part of larger creations or thoughtful gifts.
* **Garlands and Mobiles:** String several spheres together with fishing line or fine thread to create charming garlands or mobiles. These are perfect for decorating a nursery, a party space, or even your craft room.
* **Tabletop Decorations:** Arrange a cluster of spheres in a bowl or on a tray for an eye-catching centerpiece. You can also scatter them around as decorative accents.
* **Embellishments:** Glue a small sphere onto a greeting card, a gift tag, or even a plain tote bag for a unique, handmade touch.
* **Stuffing for Larger Projects:** While not traditional stuffing, small, deflated origami spheres can be used to add shape and structure to larger fabric projects like stuffed animals, giving them a more rounded, solid feel.
* **Thoughtful Gifts:** An origami sphere is a lovely, handmade gift that shows you’ve put time and care into it. You can gift them individually, in a small decorative box, or as part of a larger handmade item. Imagine gifting a set of differently sized and patterned spheres tied with a ribbon – it’s a truly personal present.
