I have had a lot of trouble with this loom dropping a tie up hook. It's a Macomber 10 shaft loom and is usually a great work horse. But some times I get happy feet and things just jump off. So I have gotten a mirror to help me check the back side. I am still working on my Single Two-Tie Woven on Opposites Without Tabby scarf. That is a very long title for a very pink scarf.
