Holly, I agree with SewBizGirl - the light one in the bottom right corner is too light but would work great with the neutrals. I like the other two for the dark purple. I really want that magenta! I am having trouble finding one I am happy with.
Enjoying seeing everyone's fabric choices and all the 4-patches. I thought I would be farther ahead than I am. I know, I know - it isn't a race but I just thought I would be whipping through those easy-peasy 4-patches and I would be done in no time, but it hasn't been the case. Guess I better quit "oohing and awing" over everyones' fabric choices and 4-patches and get to it. Happy 4-patch sewing, everyone!
