Sleying the reed for the fabulously ugly scarves. The pegs hold the “cross,” which is how weavers keep the yarns in order until they are put on the loom. Otherwise, you get a tangled mess. (Sometimes you still do!) For years I held the cross on my thumb and index finger until I found this great little gadget made to fit on the front of my loom. Now I don’t have to thread the whole thing in one sitting!
