I spent $1.25 on the cloth and $6 on the fabric glue. Mostly glued, little stiching since I'm lazy. I was toying with waxing it but why? It really does work well, though. I can toe strap it to saddle rails if there's no bag handy. I am clumsy and drop little bolts, washers and nuts and they are hard to find in grass and weeds. Leaving the roll flat gives me a place to keep stuff when fixing a flat or whatever. Somehow I misplaced my Lezyne pump and bought another one, then found the first, so I had to make another tool roll. When I go out of town I also stick an innertube in there, but since I have bikes with 16, 20 26 and 700c wheels I only do it when I will be gone for a while. That blue thing is a bit of paper shop cloth, which is good for abdominal emergencies.
