This is what I do...
Since I use my Sizzix to cut the acetate into circles, I don't have a tab at the top...I use my smallest hole punch (usually one end of the buttonhole punch - the space between the hole makers is a perfect depth for the hole in the acetate...just line it up so the top "punch is just outside the acetate and squeeze!) then I string a piece of clear elastic beading cord through the hole, roll the acetate and insert it in the ornament, replace the hanger part and tie it to the gold loop in the ornament hanger...trim the ends as short as possible...once you wrap the ribbon around the top, you dont see the ends. HTH and makes sense...
duh...I wonder if my oval tag set for Sizzix would work...the hole is already there...something to add to my to do list!!!!
