Prism--treat yourself to a couple of books by Angela Walters--Shape by Shape and Shape by Shape II. I also love to refer to my Deloa Jones books on sampler, sashings, etc. And Amanda Murphy also has some great "reference" books on quilting. Besides great ideas, all 3 of these use designs that are actually doable with hand guided machines! also check out Kris Viera, "Quilterontherun" blog--she offers every Friday a block with a way to quilt it with only one stop/start. When I'm stumped on a quilt, I'll take a picture and print and then get my plastic sheet & dry erase marker out and start doodling.
