30 dollars EACH? That seems excessive. Really too much for an embroidered Patch to sew on a shirt, or does it include the shirt too? That sounds more on the line of what a rock concert tee would cost, or am I behind the times? I'm thinking of the 1970s ones my son went to then.
I'll bet that the ones on this forum who make quilt labels could help you a lot with the different machines. Ones they like and dislike.
