All of my fabrics seem to be in the lighter ranges. Or in the bluer green ranges. In my entire yardage stash, I have only one green that's the 'correct' shade, but I don't want to cut the yardage (trying to work through smaller strips and scraps first) and that yardage has brown-shaded feathers all over it which I don't think will set well with the other colors.
The only fabric I've purchased for this project is the backing, two quarter-yard pieces of lavender, and one piece of neutral. The rest is all from my stash and I'm good with that. One of the fun things of doing a mystery quilt from scraps/stash is that one can play with color variation, so mine will have lighter greens than what was called for. It's still in the same family, but may give a slightly different look. We shall see.
Happy New Year!
