Maybe knitters are afraid of weavers because they don't have the vocabulary down.
I mean, people who talk about beating are kind of intimidating, right? (Beating is what you do to place the newest line of weaving, firmly or loosely, next to what has already been woven.)
A friend of mine one remarked that men aren't afraid to add to their sets of tools for their hobbies, but women seem to be reluctant about it.
Obviously, I did buy them, mostly because I had this lovely, fat, fluffy handspun yarn I wanted to use for weaving, and if I ordered them all at once, I had a better chance at free shipping.
(Oh, free shipping. How many times have I fallen to your wiles?)
You can figure out which heddle to use by taking the wraps-per-inch (wpi) of the yarn and dividing it in half. You then use the reed with that number on it. I use a clear gauge to determine wpi, since I'm hopeless at doing it with a ruler.
The yarn was pretty much a 10 wpi, so I used the 5 DPI reed. (That's Dent Per Inch, not Dot Per Inch.) This determines the warp half of the sett - which is how much yarn is used in each square inch of fabric.
I use a small, two-inch gauge to check how firmly I'm weaving the fabric as I go. I aimed for 5 wefts per inch (actually called picks per inch, or PPI), and actually hit it (for once, I tend to beat too gently, but I think that's better than too hard). This is the weft half of the sett and can change every time a pick is added.
Every third pick, I added a nubbly, art-type yarn along with the main yarn. I'm really happy with how the two worked together. I kept the drape and hand of the fluffy yarn and got some extra texture and color out of the art yarn.
I have a lot more of both yarns. I'm considering repeating myself, I like this so much. Or, I could use the art yarn differently (maybe even chancing it and using some for weft).
Ok, now I have to try that. I'll let you know how it goes.
P.S. - The Shed is the open space in the loom where the shuttle is brought through to creat a pick.
