The diamonds quilt is too long for the challenge. Despite suggestions from TMOTH, I'm not cutting it off or taking off the last row of goldenrod.
I did some rooting around in my stash and came up with a biggish panel of solid black (I think it's linen), a strip of satin brocade with goldfish, some solid burgundy cotton brocade and solid tan satin. I'm going to applique some water lily leaves and one white bloom on the black part, and use the burgundy and tan in a diamond pattern down one side. It'll be bold, that's for sure!
Photos soon, I hope.
