I sponged the edges and set them aside . I used Scotch tacky adhesive and applied a generous amount ( not too much , not too little ) to the front on the frame , lined up the cardstock and gently pressed it to the frame . Allow a few minutes to dry .

Question: Why might I be doing this ?
Answer: To glue cardstock to the wall .To frame a picture .To sell Scotch tacky adhesive .None of the above choices .
