To attach the lace to the card I have a technique that secures the lace without glue show through. Using an old credit card, smear a thin layer of Tombo glue on an acrylic block or something similar. (The image below shows the block smeared.) Place the lace on a firm, flat surface, 'Stamp' the back of the lace repeatedly making sure the edges are well glued but not filling the gaps. Reglue the block if necessary. Attach to the card. Wash the glue off the block as soon as you are done.
Here is the card.....
