I have had a lot of fun with using camo fabric. Get one focus piece and combine it with complimentary patterns and colors. Anything nature works. I have also used small checks in complimentary colors as well as plaids.
The most fun has been using a Alexandra Henry "Camaflague Ladies" fabric in a quilt. Probably strictly adult.
It is the black sillioute of an unclothed lady sitting. You have probably seen it as a bumper sticker on a pickup.
You don't have to be fancy with the patterns. I have one version that it is just strips sewed together on the diagonal and then used what was left over from trimming for another quilt.
Oh well, I could go on and on.
