We made a frame for this Christmas tree advent calendar canvas!  Each of the gold balls on the tree and the presents around the tree have metal discs behind them.  Ornaments have been stitched for each of the balls and presents!  These ornaments are finished with magnets inside -- so that they are attracted to the tree canvas!  The frame is made with a box attached to the front--for the ornaments to be stored before placing them on the tree!
