Finishing & Helpful Tips

- Clean Color Changes: For the neatest results, change your yarn color at the beginning of a new round right inside a corner space.
- Weave as You Go: Securely weave in your yarn tails with a tapestry needle after finishing each color change to save time at the end.
- vBlocking Matters: Pin your finished squares to measurements and steam or wet-block them to achieve crisp, professional-looking corners before joining.
