So here is the carpet thing. Since I don't really do much fence jumping these days, I have recreated my original design using a bathmat. The mat is about the same size as the carpet would be. Instead of an adjustable clip-type belt, I am using a standard piece of tube webbing tied using knots to allow the user to tighten it while wearing.
1. You will need a cut of carpet, webbing or belt (about 150cm?), and some sort of bungee cord.
2. Tie the webbing so you can adjust it once worn. Make sure to include the bungee inside the loop of the webbing/belt
3. Place one half of the loop inside the carpet's short end and roll
4. Position the bungee to it holds the rolled carpet in place
5. Sling it over you back and tighten the shoulder belt to comfort
The idea is to be able to easily deploy the carpet and place it over barbed wire. To go really fast, I suggest the clip style belt but this works only a few seconds slower. You are relying on the substraight of the carpet to protect you from the barbs so it is wise to choose a thick piece of carpet. I place the fuzzy side down (onto the barbs) to ensure it does not slip when deployed.
