A while back, someone posted several pictures of the same quilt in different colors. I jotted down basic info, but now am having a problem actually doing it. It was sewing 5 2.5" strip together, then cutting them at 10". Put together one horizontal, one vertical, etc. I have done all of that, but here is the problem. The picture had sashing. Since these pieces are 10" one way and 10.5" the other way, how can they be sashed since they are always 1/2" off?
