One of my side-gigs is making buttons. With high quality laser printing, I've been doing it for 10 years and have plenty of experience making them look great! I've always tried to help artists and bands (more than I probably should).
100 x 1" = $23
100 x 1.5" = $25
100 x 2.25" = $37
You can order them on workerbeerecords.com/buttons or if you contact me directly, and I think the project is cool I can give you a discount.
