This is my first project using silk. It is 20/2 muga. All is fine up to the point where I am tying on to the cloth beam. I can't seem to get the tension even across the bouts of warp. I think it is all good, then recheck and it seems like it is slipping through the square knots. I am using two 1/4 inch groups to tie together. Do I need to make a surgeons knot for the first knot on all the groups and then come back and finish with an overhand knot?
