Finally I tried a woggle with an image engraved onto it. The world scout emblem is readily available on the interwebz in vector format so it seems a logical choice. Leather can engrave really nicely if you get the power settings correct and this one picked out a lot of details. Dominic poppered it again for me.
That was my little detour into leather woggle making, here are the files if you want to make your own. (svg here)
