Yesterday, I found the greatest thing in a thrift store! 3 Speedball block printing kits, all different (basic, deluxe and fabric), all still sealed in plastic wrap. I got all three for $17, and according to Amazon, it's worth over $150. Two bench plates, 3 brayers, 3 lino cutters with 10 blades, seven inks, three lino blocks and two rubber stamp blocks.
So that's kept me out of trouble for most of today and yesterday. So far I've only tried the rubber stamp material.
