There may be a pattern somewhere, as I was inspired by a few pictures on Pinterest. I just made mine from all the same sized pieces, which in my case I cut at 2.0x3.0 inches for a finished size of 1.5x2.5 inches. The two similar quilts were made with the same sized pieces, but one was made in blocks and the other in loooooonnnnnggg rows. I recommend doing the blocks. I suppose that I could have cut out background pieces in specific sizes for the second one, but just went the easy way of sewing the required number to get to the edge and trimming the ones that needed half a piece cut off at the edges.
