2. Slip stitch along the outer edge:
   • Insert hook into first stitch, then into the stitch directly opposite on the other edge.
   • Yarn over and pull through all loops.

3. Chain 1 and fasten off.
4. Bring the yarn tail to the inside through the center hole.
5. Stuff the amigurumi generously, especially the corners.
6. Using the long tail (from the start), sew up the opening with a yarn needle, picking up one loop from each side for neat stitching.
7. Tie a knot to secure and hide the excess yarn inside.

Conclusion

You have now created a cute rainbow amigurumi! Scale up or down by adding rounds per color or beginning with a larger initial ring. This project is fun, versatile, and brings a burst of color to any use!

Pattern Correction

• Staggering increases (alternating starting point each round) prevents corners for a smooth arc shape, as opposed to traditional flat circle increases.
• Ignore any “fake stitch” caused by slip stitching; always join to the true first sc.

Tips

• Work tails into the stitches as you go to secure colors.
• Leave a long starting tail for closing/sewing.
• Stuff firmly, especially the corners, for a neat shape.
• Use safety eyes or embroidery for child-safety.
• Adjust stitch count or number of rounds for desired size.
