Learned this time-saver at a workshop a few weeks ago:
When securing the warp on warp board, use pot holder loopers to "tie" the warp in places needed. Wrap the looper around the threads then "tie" by slipping the looper inside itself and pulling tight. Warp is held tin place.
This method replaces the tying of string or thrums around the warp. To take off, you simply pull at the looper. No more having to find the right end of the string/thrum to undo ... or the nightmare of the string/thrum tightening into a knot and then having to cut it off.
I also use the loopers - rather than string/thrum - to count off my warp as I am warping.
This has become one of my favorite hints thus far.
I can't take credit for it ... nor can the instructor as he generously informed us one of the ladies in the Arrow Rock Guild, Missouri, came up with it.
Hope you find this useful.
