The original shower mat is transparent. I took this picture after I used it as a stamp. Besides this shower mat I used bubble wrap in 2 different sizes.
First I used the bubble wrap. Paint was applied with a brayer. After that I used the shower mat. This is how it turned out:
The examples I showed you this month are by no means all the items you can stamp with. For instance potato mashers, grids, placemats. In other words, everything which is flat and has a nice pattern or texture can be used. And don't forget most of the stamps I talked about this month can be used not only with paint, but also with discharge, soy wax or thickened dye.
