So after some fussing about with my tackmaking supplies, I thought about other performance ideas I'd like to try. One of the things that came to mind was a mule drawing a coal cart. I live in the heart of coal country in Pennsylvania and even have a bin of in-scale bits of anthracite in the basement. I've never really made a proper wagon before - I tried making a mini hay wagon once and it was a disaster. Any tips, tutorials, anything like that for a beginner?
