Your squares need to be 8 x 8. I measured my quilt ....totally forgetting about the seams :) If anyone has cut their fabric let me know. Since it's only been a few hours I hope we're okay!
One more note....if you want to make a Quilt (like the butterfly one) ....with these swaps. It takes 80 of them to make a full size quilt. If you swap 10 or 20 or even 30 at Convention....you can return home and make the rest of them with fabric of your choice. Don't let them numbers scare you I made 35 of them in about 4 hours.
Stay tuned......I'm working on instructions and a video this week.
