There are many excellent books on crazy quilting and if you ( or someone you know) has an embroidery machine that is a quick way to do fancy stitching or even just a newer machine with lots of decorative stitches. Mix and match as they say. I think the tutorial was "de-boning a shirt" which showed how to cut out seams and salvage as much material as possible. It seems like the T-shirt logos on interfacing should be okay, but I've not done it.
