Trying something new soon. Elaine over at Elaine Adair Pieces inspired me to paint a 24" square quilt block for my new office wall. I am going to mark the lines between the colors with this tape and just leave the tape in place. Forever.
I got it at Advanced Auto Parts. It is a "detailing" tape, solid black, and it's 1/4" wide. I am going to paint the sides of the board black, then lay the tape down to distinguish the different areas of color. I'll paint the edge of the plywood black and hang it with "Velcro" command strips. Forty feet for $5. Hope it is enough.
