Well, I've used looms before, although I don't have one. Floor looms, 4 harness, is what I had. Yes, the set up is the longest, finicky part of it! Stringing each thread through the heddles (the wire/string things on the harness') and then the beater, and evening up the tension. But it's fun, once everything is set up and you get a rhythm, and watch your fabric grow! It's not 'hard' per say, to warp a loom, you just need to take your time and do it carefully, and make sure you 'control' the warp to keep it from tangling up. Have fun!
