I guess i'm in the minority here! I like making them, I make them for all of the graduating senoir in our church youth group. I only charge for the materials. Mine are very basic. I let the t-shirt tell the story. Kids don't really care about the quilting or sashing. I just iron on interfacing, cut out 15 inch squares, sew them together, back with fleece (inside out style) flip it, and zig-zag over the ditches.
**For anyone interested in 'Project Repat' ... A friend had one done there and was happy with the results. No interfacing, backed with fleece and no quilting to hold the sides together, but she loves it.
