One of my pledge bros recently bought a hoodie from
www.stitchzone.com. He totally loves it especially the fact that he had them custom stitch our fraternity's crest right to the back of his hoodie. It looked awesome. I think the crest was like 10-12 inches on the back. They didn't charge any design fee or require any minimum. If you want anything custom, I would buy from Stitchzone.
