So I came up with a painting technique that gives the look of marbling without actually floating pigments on liquid, as seen in traditional marbling tutorials. I've been experimenting for some time and finally am very happy with the results!
I made some leather wallets that are hand painted and sewn as well as some different sized clutch bags with a marbled pattern. I'm so excited about how they came out and will be working on new color combinations and patterns on different accessories and jewelry soon!
Here are some tests of different paintings I did.
And after testing here are the wallets!
