Under Padding

While walking through London Drugs I came across a product called Easy Liner Solid, which is a solid non-slip closed cell foam shelf liner. It is about 1/16 thick and spongy but firm.

I picked a roll up and am using it behind my paintings now. Being beneath the paper it gives a very good cushion when painting, it holds masking tape well and doesn’t seem to tear when tape is removed.

I did use contact cement to glue it down to my backing board so there is no way it will slip.

If you see it you may want to pick a roll up and try it.
