Sunrise Quilt Studio

This is a Double Wedding Ring quilt top that I purchased this summer. It isn't that old, but I liked all the different fabrics in it. It is machine pieced and looks like a template was used. The pieces in the rings have rounded edges. There are a wide variety of fabrics in this top. I can identify upholstery fabric, single knit, damask, barkcloth, seersucker, flannel, and cotton, along with a couple of pieces that look like feedsack. I thought it was interesting that a few of the patches were sewn in backwards. I wonder if it was done on purpose?
