I believe The Wizard of BC may still have some patches available that could be sewn on a rugby or polo shirt.

Or check with him, I assume he has the design lay-out set and would be readily adapted to be embroidered on shirts as well.

Unfortunately he may not be ready to take on another project right now as he is working on the tartan.
