Bseed, If you have access to an inkjet printer you can buy transfer paper, print your own design on it and iron it on to whatever you want. (Don't forget to print a mirror image of the design.)Ironing on a large design can be tricky with a hand iron but should work fine if you can use the presses often seen at t-shirt stores.

If there is a large version of the Mudcat logo perhaps it could be made available for us to download.
