Well, ..., this has been interesting. My original warp at 10 ends per inch produced a weft-dominant fabric that seemed too thick for a scarf so the first eight inches turned into a sample. I resleyed at 12 epi and tried again. After washing, the original 10 epi fabric was nice and soft and seemed to have a good drape, although thick. I think it will make a good scarf. The 12 epi was too stiff. So, I'm getting a lot of practice sleying and tying on. I'm now back to 10 epi and weaving away.
maus's comment talked about alpaca snapping - boy, was she right! I got about five inches into the scarf and within a few picks both selvages broke. With the pattern I'm using it's not easy to weave in the replacement thread without having it show, but I did what I could. I'm now trying to weave closer to the reed so there isn't so much abrasion on the selvage, and I'm trying a little less tension on the warp plus trying as best I can not to pull the yarn against the sevlage. This last part is hard because the yarn is sticky and if I don't pull some the selvages get loose and loopy.
This scarf is going to use tons of yarn for the weft and I don't have enough of any one color, so I'm weaving stripes of different colors and I'm blending them between stripes by using two shuttles and alternating picks. I like the effect. Maybe I'll have a photo with tomorrow's post.
