So, I shall share what I've learned so far so that any of you proto-weavers out there can learn from my mistakes.
- Have Good Lighting
- Check the warp for mistakes by treadling against a lightly tied warp BEFORE you tie that last knot
- Don't use a squishy thing as your warp separator on the back beam
OK, now on to the second item, testing for errors. I tied on the warp, front to back, and made all the knots nice and tight, and then started weaving in the front band. I quickly found out this shiny pretty warp was not quite right. Dang it! I ended up having to undo both the first quarter and the last quarter to fix threading errors. Undoing those knots was a pain, and of course then I had to undo the rest of the knots once things were fixed because the tension had become very uneven. So, NEXT time I'm going to be doing a test before all those little knots are tightened down. You have been warned.
And third, about that squooshy thing. Here's what I'm talking about:
That squooshy thing is the thin foam padding one uses under futon cushions to theoretically keep the cushion from sliding. I can safely say that it is as effective as a warp separator as it is an anti-cushion slider, which is, not at all. If you're not a weaver, you may be asking "well, um, why would you want to separate your warp anyway?" Some weavers don't, and it works fine for them. In my self-taughtness, the books I've read suggest that having something between the layers of warp that get wrapped on that back been is a Good Thing (tm) because otherwise the tension gets a bit wonky as some threads sort of sink in to the previous layers. Why did I use a squooshy thing if the purpose was to have an even tension? I was having a stupid moment. I am paying for it now. Let my purpose in life be as a warning to others.
Since we're on the topic of errors, let me show you what a gradual change in tension does to the fabric. You saw yesterday's picture of the first part of the scarf. Things seemed pretty even, no? Well, over time, it starts to look like this:
Tune in in a day or two when I show pictures of my latest spinning!

Ah well now it all makes sense!!
I'm certainly no grand master when it comes to weaving, but perhaps I can share a few things with you that might make your life easier ;-)
1. Now I understand what you call a warp separator. It is necessary, more with some yarns than others, but the best material to use is simply lining paper (sort of like a plain wallpaper roll...I'll take pics of mine when I get a chance....and when I finally get a blog going!!) It's very easy, rolls on perfectly and can be re-used over and over.
2. Tying on: I generally work with lace weight yarns and typically sett at 20-24. It can be hard to see mistakes, especially in the beginning and it is also very demoralizing after having spent 2 days setting up the loom!!
So, as a rule, I take my time threading and sleying, but I also do a systematic check at the very beginning: I presume you always start by weaving a plain weft made of relatively thick yarn, to "set" your warp into shape, right?
In addition to that, I also weave roughly 4 rows in plain weave with my working weft. Any mistakes will be obvious then. I then re-sley, re-tie...whatever the mistake is.
When done, all done, it can be easily removed. It may sound time consuming, but removing 4 wefts is far easier than dealing with mistakes down the road.
Another option (if it you do spot your mistake too late and don't have too many of them) is simply to break the warp thread and replace it with a floating warp thread (same as you would for a floating selvedge) and secure it into the already woven fabric with a safety pin, which can be removed later.
3 Tension issues...I am well familiar with that one, since I often work with multiple yarns and a single back beam!
If you need to adjust the tension on part of your warp, pass a dowel behind the slack warp ends, against the back beam and add necessary weights to it, so as to even out the warp as desired.
Ok, this is getting long now....hope this helps!!
Cheers!
I'm also a beginning weaver - today I warped my loom for about the 4th time, made a new stupid mistake, fixed that, thought I had the tension fine, but am having similar issues to yours. I walked away from the loom, but tomorrow, I'll pick it all out (only about 4") and retie it all. Sigh. You're right, though, I assume it will all get better!
