I am getting ready to warp my 4-harness loom for the first time.I want to make a scarf about 14" wide. My warp thread measures 18 threads per inch so I will be cutting 252 warp threads. My reed is a 12 dent reed. Should I put 2 threads in one dent, 1 thread in the next, 2 in the next, and so forth? -Ann
