Today I was determined to finish my black and white piece....I've really had some great fun working on this piece but at times...missed working with color...even my colors which tend to be muted. I left lots of room all around - wiggle room....as I planned to stretch it over a pre-stretched canvas. At first I was using ribbons to mark the 24" x 30" size and to see where I should turn each side under. The ribbons weren't working as I could still see beyond the ribbon and visually, couldn't get a good feel for where to end it. I thought of using black strips of fabric that could be moved in and out from the edge.
