Thanks!
Spacing is 1/2 inch on the top bar and about 1/3 inch on the sides. I'm using 3 strands of mohair, because it is such fine yarn. I'd like to try some thicker yarn another time, when I get some.
I've never done any other weaving, so really can't compare. I do like to see it work up fast. Definitely faster than either knitting or crochet. I used to do a lot of both, but it made my hands cramp so that I gave it up.
Some day I'd like to try using a floor loom to see how I like it, but this isn't a good time. Anyhow, I think once I get the hang of this it will suffice. A person could sew two triangles together for a blanket too.
