Sunprinting is a great excuse to do some plain air painting! Gather your paints on a sunny warm day and go outside. I generally paint on a plastic surface, so I can just spread out on any table.
Most washable paints will work with this technique. The best results will come when the paint dries the quickest and the item you use is in good contact with the wet paint. That said, you can do this inside overnight until the fabric dries but the result will be more hazy and less defined.All of the fabrics used are pima cotton and PDF. But you can use any washed non-textured fabric. Texture interferes with the printing results. The fabric above uses cheesecloth for it's print.
Sunprinting is part of my Fab Fabric Painting Workshop.
