This is not a post saying you shouldn’t buy band merch. Not at all! This is a big support for bands.
This is more a rec for giving a new life to old or new shirts. With some fabric paint (you can get pens also) you can get really creative. This one I’ve done for the album Bright Flight from Silver Jews (Tennessee lyrics on the back).
One artist I inspire myself a lot is Katie from @sandw1tchshop (instagram)
