try this if you can't find what you're looking for:
plan #1. match up the background color in a solid. use that in place of the green.
find a small or medium print that features that green as the background fabric. use that in place of the yellow. alternate the blocks.
plan #2. someone here (patrice? loretta? moonpi?) knows how to design her own fabric. beg her or promise her housework for a year if she'll share that secret with you. i think it's patrice.
