Dear Folks, I took the easy way out of grid lines on GG and used the 1/16th inch wide self sticky tape that graphic artists use to make layouts. If I need to change the pattern on the back of the glass it just peels off and I can re-apply more. Works to mask off small format viewfinders as well. Idea courtesy a book on photo tips - possibly Steve Simmel?
