I've decided to take this quilt "back to the drawing board" per say (ha ha). I had thought about adding a 6" border around the edge, but then thought I could just add another row of blocks along the side and at the bottom and then put a narrow binding around it. I'm thinking 7 squares across and 9 squares down. Originally it was 6 squares across and 8 squares down. So now I need to cut 540 more of the 1-1/2" squares (36 squares per block). It's a good thing I'm really enjoying working on this quilt or this might have been a major set back.
Anyway thank you all for all of your suggestions and ideas. Will keep you posted.
