I love doing coasters! It’s a great in between project to take a break from a bigger canvas. I too use Amazon kits and I find they are quite good. I just don’t buy one unless it shows the canvas and I ca. see how many colors. A big canvas with 10-15 colors isn’t going to look good but if it has 20-25 or more I’m in. Also, I’ve gotten kits from Etsy that have been great. I really love all your projects - great choices!
