Most blocks can be made into just 2 colors. I like Drunkard's Path (its one of my favorites) like others said. Lots you can do with this block. I just purchased a pattern from Eleanor Burns - Lattice Work. The main part of the quilt is 2 colors and then the border is a darker variation for distinction. Really a pretty pattern.

I made Jacobs Ladder using only 2 fabrics. Medium to darker blue for the ladder and lighter blue for the back ground> Really made the ladder stand out.

thanks for all the ideas!!! we have w-a-a-y too much talent on this board.....and the nice part is, everyone likes to share their ideas!!

This quilt will be for my Vet for Christmas. I've already done a purple/white Jacobs Ladder, Monkey Wrench, Irish Chain but will give the Hunters Star another ''look see''. I am leaning towards the Night and Day tho....it was a great pattern and a great look too!!

Night and Day is pretty, post your picture when your all done.

I googled two color quilts and found this pic of a Hunter's Star quilt in two colors. Winding Ways would be pretty too.

Hunter's Star is a pretty 2 color quilt. Drunkard's Path also works up well using just 2 colors. I'm sure there are a bunch of others but these come to my mind first.
