>> Oooh, I like the idea of friendship shirts! I'm keeping that in my back pocket for next time.<<

Yay!

>> Dharma Trading Co was our source.<<

Yeah, that's the gold standard for professional dyes. Go you!

>>But I have the terrible tendency to go, "I need green and brown and black specialty paints for my goblin miniatures, but look at this full-spectrum paint set on sale! It will be worth it so I can paint my fire genasi miniature next.<<

Failure of extrapolation. Those would be reasonable choices if you followed through. Study your actual use patterns, that may help with targeting.

Also, look up. Do you have things like bookcases or china cabinets that you have not already put things on? If so, you've got another option for in-progress art projects. You can put things in boxes or on boards up there. A corner of bookcases will support a square board if it's not too big. And you can use something like "quake hold" putty to stick your minis in place so they don't tip over.
