I used the new Crop-a-Dile and punched 20 holes in each side (you'll break your hand if you try to use a regular paper punch). Line up the spools (or loose scraps) of ribbon and pull a little through each hole. There's still plenty of room in the middle for the Making Memories ribbon cards!
See that luscious new ribbon on the lower left side, it's a brand called Elements and I got it at Hobby Lobby.
In a separate box, the Heidi Swapp foam stamps line up on one side (a little tight but do-able), and I purchased a set of 24 acrylic paints (at W-Mart - eee gads!) in cute glass jars for $9.98.
