When we’re sewing leather (e.g. making shoes), rather than waxing the thread we use coad. Medieval coad was a black wax likely made with pine pitch, rosin and beeswax. Coad is used instead of just wax because the rosin and pitch act as a glue to seal our stitches in place and stopping the thread from rotting, while the wax keeps the coad malleable and lubricates the thread so it can be pulled through the stitch holes. This video shows how to make coad using a more modern white wax recipe. We use this instead of black wax because it’s hard to get good pitch, and white wax is much less messy when sewing at home!
