Some have asked about the grab bars and ladder runs
Basically they are just K&S brass wire (can be found at most ACE hardware stores) but any apporpreate sized hard wire will do.
Under the wire is a shaped head pin from the bead making aisle in walmart.
Small holes are drilled in the plastic and the wire is glued, inserted and folded over on the backside.
Harbor freight has needle drill bits. they are very fragile so pick up a extra pack.
(conversely you can clip the sharp end off of a needle and use it as a bit, it actually works pretty good.)
If you use them with a power drill make sure the drill can go down to "0" bit size.
