It's not really cheap. Especially if you want to offer stitched and not printed ones. Some time ago I bought a customized Patch, the Patch itself costed like 7 bucks but I payed the company nearly 40 bucks to get them to program it into the stitching machine. But even if it's only possible to get one size and shape I'd need a lot of them. I got 2 Backpacks, multiple Hoodies, a Basecap and multiple Shirts that need to show that Patch!
