|I picked this clamp up from Home Depot over year ago, thinking that it might come in handy (pun intended!) whenever I had an occasion to need a "third hand". I had forgotten about it until today when I started a hand-rolled hem on a 4 1/2 yard long founce cut from georgette. Claire Shaeffer suggests holding the section of the edge you are working on taut which makes it much easier to manage. This clamp works great for this! I think I only paid $1 for it from a bin at Home Depot, but any hardware store should carry them.
