Somerset Beeswax in a handy block of approx 23g.
Beeswax is great for waxing thread for bookbinding and leather crafts, can also be used in many other applications such as mixed media and encaustic art. Melt a small amount with some carrier oil to make a polish or apply to paper for a faux vellum appearance. 
This wax is melted and molded by Janie from local wax collected in Somerset.
