what about collecting batiks with green and purple? Or really any collection with green and something added in? I've been doing a bunch of scrappy quilts lately and there are some patterns which are quick and easy to do. I'm thinking the disappearing 9 patch or split decision or simply squared. The 9 patch uses charm squares and the others use 2 1/2" strips (or jelly rolls/bali pops). I guess a lot depends upon your future DIL and your son's taste...are they more contemporary or traditional? what's their "design style"?
