DewDrop Inc, by Toronto-based artisan Liat Weiss, has a whole bunch of DIY kits. And for every purchase made, she donates $1 to Pancreatic Cancer Canada.
Kit includes: four polymer clay colors (roughly 1.2 ounces each), one parchment paper, six earring display cards, 12 earring studs (choice of silver or gold), 12 silicone earring backs, 20 jump rings (silver or gold), one wooden pick, one circular cutter, one wooden roller, two sandpapers, two alcohol prep pads, and one tube of adhesive (optional).
Promising review: "A birthday gift to myself! This awesome kit is small but mighty. It gave me all the tools I needed to get started right away on a craft I've been eyeing for a while, without needing to worry about researching the supplies I needed or choosing among tons of clay colors. The step-by-step instructions and inspiration were easy to follow and super helpful, without being too much information. I'm super excited about my black and white cookie studs (in progress)! Shipped quickly, too." —stephaniegomory28
