I am making a pinwheel quilt and I cut some of my squares too large... now I have to trim trim trim. Also, I did not get enough of the white... back to JoAnns I have to go... I also need to pick out fabric to use for stashing and side panels. Wow is me... lol Pick a pattern, pick up your scissors/rotary cutter, and proceed. Mistakes are for creating your own unique pattern. Go girl!!!
