This frame created from the two paperboard packaging included in tights. In a piece I cut a square inside a thickness of 3 cm I created several rolls of paper sheets using straw as described here. http://lila365idees.blogspot.gr/2013/03/frame-of-paper-wrapped-wire-beads.html. Using hair glue stuck to the four sides of the paper rolls six on each side as shown in the layout of the windmill. Leftovers snip diagonally into each corner. Behind the front opening glue a rectangle piece slightly larger than the opening of transparent plastic sheet to protect the image. Stuck the back to the front at the left and at the bottom. I cut
with cutter four shapes and stick them in the four compounds. (This is optional). I cut a piece of cardboard in the shape of the delta and glued back on top used for hanging. If one wishes can spray the frame with acrylic spray.
