Queen, great photos of your shirt quilt. That is exactly what I plan to do with this quilt BUT quilt each block before making the full rag quilt. Sarah has 30 shirts so far for her quilt, will be either a queen size or make two smaller ones. Will let her decide when we start laying things out. I am thinking it would be more useful to her as two smaller ones and actually use them.
I make tiny shirt blocks from very small logos and those are cute. Took our farm embroidered logo and used a JD green shirt to create a tiny shirt block for another quilt. That tiny shirt is the memory block because our son passed when GD's were 3 and 6 years old, youngest Sarah is now 18.
