I just finished a detail picture (Burrowing Owls) using 1/4" Basswood. I used the peal and stick shelf liner, clear. It worked fine as far as no lifting while scrolling, but when it came time to remove the pattern, that was a different matter. Took me over two hours to get it off, having to work very slowly and cautiously. In several places the paper would come off but the liner was still stuck. Really hard to see it because it is clear and much thinner than tape. I Only saw it was still there when I held the picture up to the light and the light would reflect in it. I finally got it off without losing anything, so I sanded the picture as I always do, and gave it a bath in MS/BLO. It has been sitting for three days drying. I picked it up today to look shelf it over before applying Deft over it and under the light I can see residue from the liner that I could see or feel before. Not sure what I will do now. Guess sand again. I don't think I will use shelf liner again on a detailed picture. If I do, I will try some colored liner, Not sure why it has to be clear.
All I am saying here is, yes it works, but on real detailed pictures, and soft wood, like Basswood, I for one will go back to the blue tape. I will still use the shelf liner in other cuttings.
