This is what I do except I use a glass carrier for 4x5.

I spent some time one weekend making a bunch of masks for 35mm and 120 out of black construction paper that let the rebate area show. It started out as making a mask for 127 film, but I just kept on going once I had the paper and Exacto knife out.

Like Rick I found that I don't really like it that much now that I've tried it. But if it words for the subject, then go for it.
