First paint the frame black (or match the color of the lace you picked from)
glue the first layer of lace down
take the ribbon and cut it to fit on the inside of the sides of the frame to cover the glue marks.
measure the length of the frame and cut a rectangle about 2 inches wide and the whole 1/2 yard long
gather the rectangle in the middle and use the hot glue gun to glue the middle of the gathered fabric onto the middle of the frame's sides.
now decide where to glue the flowers and pearls down, then glue them in place and enjoy!
