According to my directions, I'm supposed to resley my reed from 2 threads in a 10 dent to 3 dents in a 10 dent. Since I had to pull the threads out of the 10 dent reed anyway, is there any reason I should keep the 10 dent reed and do 3 threads per dent OR would it be better if I just used my 15 dent reed and put two threads per dent. Same epi, right? It's not hard to change out the reed on my loom. Still learning...
