Unless you intend the item(s) to be gifts (free), then you should, at least, cover your costs-stock, parts, finishing products, tool depreciation, disposables (sand paper, etc), electricity, heat, etc, etc. If you just enjoy making stuff, as most of us do, then you can count your time as free (if you so choose) because you would be making something anyway and the project in question helps keep you busy. I charge friends and acquaintances, but immediate family (siblings or offspring) is free unless they intend to give the item as a gift.
