I made a really hard block one time and when it was done it was only a 10" one so I added a border around it and it really made it prettier than before the border! I hate to trim one down and lose the points also...sometimes it just doesnt come out to exactly 12.5" but most of the time you can adjust or add to get them to work in the quilts. I wish there was a link for "finished quilts" in Booms. I love seeing what everyone finishes!
