This bad boy is custom quilted with a light brown (fawn maybe) thread. I let the quilt shop chose the color as long as it blends in. I was more of a pattern Nazi a few years ago when i had this one completed but now, i like to have suggestions(choices, who doesn't like choices) but then i give the final say to the long arm master.
(Binding matches the back of quilt, the true color is of the binding, not the backing)
I made this quilt for my boys and as such i wanted a back that didn't scream i'm full of flowers and pink. Nothing wrong with pink, my oldest really likes pink but i tend to work with girl fabric because it catches my eye so much quicker than boy fabric. That totally could be because there is maybe one tiny section with 6 bolts in it for boys. (over exaggeration but you get my drift)
i have also switched to 108" "Utility" Backs. In the long run they are more economical, without cutting and piecing. Time saved, AND you have less math because length is already taken care of. I just purchased 1 2/3 yard @ $13.95/yd for the back and binding for a 50 X 72". The binding is included in the length and the sections are longer strips for less piecing. Total win-win.
