Most of the guild members that sent in photos like to wind their floating selvedges with the rest of the warp. They beam the threads on, but don’t thread them through a heddle. Here the similarity ends as they use a variety systems to weight the threads as the warp advances.
Gayle uses a box with a collection of stones in different sizes, little baskets to hold the stones and a carabineer that forms a loop around the selvedges and supports the basket. More tension - bigger rocks! Her husband says the patent is pending on this system!
Rae uses a similar system with an S hook and a couple of clamps for weight.
More tension - more clamps!
Beryl and Igor add their floating selvedges after the rest of the warp is beamed on.
Beryl uses hardware store clamps (having learned this trick at the CNCH in Sacramento several years ago). The yarn is wrapped around the two arms of the clamp in a figure 8. The clamp then pinches the yarn to keep it from unwinding. She also uses this system for supplementary warp ends that don’t take up at the same rate as the rest of the warp. The photo on the left is the system for a floating selvedge and the one on the right is for supplementary warp threads.
