You would need 1017- 1 1/2'' x 1 1/2'' squares to make 113 - 3'' x 3'' finished nine-patch blocks. No, I did not piece them individually. Barb shared a cool technique on how to make these scrappy nine patches the easier way. Read all about mine here and visit the link for the tutorial on these little jewels.
I also worked on a small quilt top yesterday. Now wondering on how to quilt this wall hanging.
Have a great weekend!
