Why not make a simple tinder pouch? Cut the suede so that it is circulat, leave a little tab at the twelve and six o'clock positions. Punch holes around the edge about a centimetre in from the edge at regular intervals and thread two pieces of crdage through the holes and tie each one to itself so that you have two seperate circles of cordage going through the same holes in the same direction. When you pull the seperate strings from either side of the pouch, it closes it up and if you then pull the tabs it opens back up. i have one for my fire steel and flint.
I can pop a picture up if you like.
