I was making the 9-patch madness and loved it. was gonna make it 4 across by five down, so got my 20 blocks made and stupid me didn't even think and put 5 blocks in the rows and now it's to short. don't want to take it all back apart, and have no more of the background fabric as it was I was short and used a different wow on the 4 corner blocks. I could make a new row with a different wow for top and bottom, will be bigger than I wanted but it is scrappy? Or I could just add bigger border to top and bottom and smaller to sides. What do you think? Thanks for any help.
