How much bigger are you wanting to make it!. I like the sublte tones. Audition a bight tone o tone to match the lighter tone. Go to the fab shop and lay out some fabs. Walk away from it for awhile, or ask for help. If you don't like what they suggest--DON"T USE IT.
Made my mother a DBLE Irish Chain, fist one and didn't like it, but finally, took awhile to find the right fabric.
