1. Where do you get your pins/charms/prints/etc made?
I use Vistaprint, Moo, Overnight Prints, or local print shops for cards, Catprint for art prints (warning: they come out dark so adjust your files accordingly), and Vograce for charms. For enamel pins and other merchandise, I don't share my sources, because I've had problems with overloaded factories. You can read more about why here.
2. What programs etc if you use
