Getting the right finishing effect can take some trial and error. I wanted to share a few products I enjoy using.
To make a crackling effect, I use FolkArt Crackle Medium but it seems it works best when paired with Ceramcoat paints verses other Folk Art paints, which I thought was odd, but you can test for your own results. Regular Elmer’s white glue works too. You just have to paint over it at the right dry time to get a nice crackle. Make a test sheet and write dry times and paints used above each test area.
