I am totally confused. Pattern says to sley reed at 3 per dent, however in video Jane says to sley first and last dent with 2 per dent. However doing so leaves only 1 thread in the last dent. In one of the old forums the suggestion is to not do the 2 dent first/last sleying. Can you advise what I should do? Would love to weave this lesson. I am a new weaver and am learning so much!
