Go to a wood yard and ask them about offcuts, for 2 quid me and Leroy got a big bag of nice mixed sizes, some hardwood. They did seem to think we were rumaging through the massive bin to choose our own kindling, this confused the Llangefni locals a bit. A belt sander is ideal to make them, about 12 pounds for the shitest one we could find in Stermat. If they exist outside north Wales.
