I have bought fabric waiting for the perfect pattern. Other times i get the pattern and wait for the fabrics to call to me. Lately I pull fabric from stash and find something that uses the amounts I have. Look for borders after blocks are made as I make them until I run out of fabric. Therefore I never know how big my quilts will turn out. Most are donated now so there are no particular requirements. Even if I have something that will work for borders, they may not be my preference. Recipients don’t know it wasn’t meant to be and appreciate it as is.
