Yvonne,
Your quilt is beautiful. So happy and cheerful looking. I teach a beginners quilting class and we have used the coping strips many, many times only have called them framing strips.I like the name"coping " better though as that is exactly what they do,cope with our uneven blocks. We usally add them to all 4 sides then use a square ruler to even the block up.Thanks for sharing this tip.
