I'm in the same boat right now. I pre-ordered a ton of the fabric (15 yards or so). I've been keeping an eye out for patterns that I think fit the fabrics but haven't seen anything yet. Fatquartershop.com has a few kits that you may be able to buy the pattern separately from that use the Dr. Seuss fabrics.
I'll be looking forward to seeing what others create with their Seuss fabric!
