This pic shows the effectiveness of fabric repeats and can really give the quilt a 'connection' factor. We want all the blocks in the quilt to show a similar relationship to one another! However, I've been known to stick in a block that looks like none of the others. I do this in most of my quilts. It is my philosophy that there is always one in a crowd that does not belong. Among Jesus' disciples, there was one that did not belong. I did this in my last tut where I placed a really loud large scale plaid background fabric that had nothing to do whatsoever with all the small scale prints in the Square in a Square quilt. However, in the tut prior to that one, the Greek Key scrappy, I was not able to put in such a block.
