Strictly on the economics, I had about $30.00 in to it, saved maybe $100.00. Fair amount of time, but I have a lot of time. I would of had these tool holders done in 3-4 days but the filming is very time consuming so projects take me over twice as long to complete. I make things mostly for the enjoyment and satisfaction of creation. I am able to put my own twist on items. I make many items for friends so they to can enjoy. The needle knot tool is one of them. I also have a pile of the oil cans. Thank you for your interest and for watching.
