Well I haven't quite finished yet, but here is the jist of it.

Slim CD jewel cases will fit in the slots under the track walls. Just line up the tabs that would normally hold a piece of paper and slide them in (note it will be a tight fit but you actually want that). On the hinge side of the case cover you will see a raised line. Use this as a cutting guide and cut along the side away from the hinge. On the other side you will see 2 raised lines. Use the top of each line as a cutting guide to cut two barriers out from the material. Once you have done this use the lines as cutting guides to cut those sections off. Repeat process until you have enough to cover both sides of both straight aways (You'll need 24 cases for the new Giant O' Layout. It seems like alot, but they are realitively cheap).

For ZipZaps and Bits this is all you will need. Since the track is wide enough for 1/43 scale cars too you'll need some extra support on the back of the barriers so that they will not pop out. This is where I am having the trouble. I want to find a material that is cheap, visually pleasing and safe for kids to play with.

If you are worried about your cars getting scratched up on the barriers you can add a thin self-adhesive weatherstripping to the barriers on the track side.
