Well done they look great, and a good way to use up scraps left over .
A lot of folk on the turning section use all kinds of fillers in their work some of it may be small cracks and is usually just dust from what they have sanded .
Others fill large voids with all sorts of things . Two part epoxy filler being one of them . The general consensus being to leave the filling raised and sand to a finish
and Bob's your uncle .
Thanks for showing.
