Hi, this is my first project on my Nilus loom. The sett is 18epi and I threaded the reed 1/2. However, every time I change treadles the 2 threads in the same dent stick together and the one that is supposed to fall won't. It has taken me 2 days to weave 7 inches because I have to untangle the threads every time. This has been quite frustrating, what am I doing wrong?
