I started marbling Saturday evening and worked until 2AM. I ended up making more than 80 papers. I first tried marbling more than 20 years ago when I got the ambitious idea to hand-make my sister's wedding shower invitations. (this was WAY beyond my skill level at the time, but it didn't stop me).
I don't remember the exact technique, but I know it involved oil paint and turpentine and supplies that were hard to find, expensive, and crazy-messy and hard to work with. The results were colorful, but not very satisfying. I used them anyway and my dear sister didn't complain.
I've since learned how to do this with liquid starch and cheap acrylic paint and I'm SO happy with the results. Supplies are cheap and readily available and easy to clean up. And since I use those cheap craft paints that cost less than a dollar, I can spring for a wide pallet of colors.
So here's a selection of what I churned out. My mail art friends will start seeing them in their mailboxes soon!
