For the cleanest finish, aim for consistent tension and take a second to align pieces before closing everything up. If your ball looks slightly lumpy at first, gentle reshaping with your hands after assembly can help it look more even.

And if you’re making this as a keychain, it’s worth making sure the top attachment point feels secure so it holds up to daily use.

Happy crocheting—and I hope this interlock ball becomes one of your go-to small makes for gifts and craft fairs!
