I backed the quilt with white minky for the softness factor. I had originally planned on using some cute paw print minky I found at Jo-Ann's for the back, but then I found out one of the parents is actually afraid of dogs. Hmm. Since I had already pieced the top with fabric containing dogs (and cats and bunnies and fish), I just nixed the paw print backing. I couldn't find minky that matched the colors on the top close enough for my satisfaction, so white it was. That plus the 3-colored binding (woo hoo, more stash fabric!) really brightened the whole quilt up, so overall I'm really happy with how it turned out. I also used basting spray, which made a HUGE difference in the whole process of quilting with minky. No shifting at all! This quilt definitely put minky back in my repertoire.
And here's one last totally awful shot. At least you can see the (blurry) animals. I quilted in the ditch for the center, and you can juuuust see the zigzag quilting on the border seam. Just to add one more layer of stability for shifty ol' linen.
