Useful Tips

Place a stitch marker at the start of each round to track rounds easily.
Change colors by completing the last yarn-over of the previous stitch with the new color for smooth transitions.
Carry unused yarn inside the stitches for less weaving in and cleaner color changes.
To keep the shape smooth, stuff gradually and avoid over-filling.
Sew all parts securely for durability, especially if using as a keychain.
