There are twister books out there that will help you with designing your own. I did the Christmas tree quilt and it took me a while after they were cut to turn them the right direction. Which I thought was going to be very basic and easy but once I started it drove me crazy. It made me feel much better when Jenny Beyer said she had to lay them out and sew them line by line so not to get lost in the design.
Good luck with your plans, be sure to post pictures.
