having gotten my head around burning wood i thought it might be a plan to attack leather next, plus, i was in need of a new wallet. so i headed out and found a yellow leather wallet to cover in bees. here's hoow that went:
i only used the thinnest of my nibs to draw these, mine is about the width of a biro and works in much the same way. i think perhaps because the leather has been treated (to be yellow) it doesn't burn quite so readily as the untreated stuff or wood, but it still works well enough.
