What are we learning?

So I have been weaving for 30 years, not all the time, but enough time to know a few things. It is always humbling to realize we don't know all that much. So after horrible struggles with this warp, awful selvedges, looping weft, my problems have vanished! What was the problem? ¡The reed! Looms hate uneven numbers and the wonky reed arrangement for 26 epi in an 8 dent reed, 3-3-3-4, was fatal. The yarn stuck together, funky shed, impossible selvedges. I now have a 13 dent reed, 2X in a dent, no problema! I didn't need the rotary temples, all is calm, weaving fast, misspicks gone.
