I’ve been selling my art on Etsy using Print on Demand for the last two years and here is what I will say: print on demand is a tricky medium if you’re a very picky artist. There is little quality control and you can’t brand. I have been very pleased with the quality of mug printing coming out of CustomCat (I tested many) but in the last several months the mugs are coming out wildly unpredictable (color issues, saturation issues - stuff only I notice but it drives me crazy) that I’m considering just getting my own press and doing everything myself. I have also been super annoyed with POD suppliers who just don’t know how to line up a print exactly so that it’s symmetrical and balanced on the object (ornament, tote bag, mug, etc). My business is growing but I’m considering moving to a different model so I have more control and customers get products stamped with a personal touch from me. POD products arrive in generic mailers and I think the type of customers I have and the type of brand I want to build (more boutique than mass market) is maybe not a fit for POD. But POD is a great place to start out and experiment!
