Here pics of the Shiva Paintstics used over textured surfaces. I cut up some old fruit baskets, the kind you get from the produce section of the store, and I used some commercial texture plates. You could do this over a stamp that didn't have very fine details, or over a stencil. If you use a stencil you may want to put a spray adhesive on the back to prevent it from slipping around on the fabric when applying the paintsticks.
Let it air dry 72 hours, heat set with an iron and then wash as normal.
I carry the sticks on my webstore http://www.prairiefibers.com Just click on the picture and it will take you to that particular product page.
