Finished warping the loom, and finally got started weaving. I'm learning many things: double-check for crossed warp threads before weaving, etc.
Tied to back apron rod:
Back beam warped...
And finally weaving! ( Notice that I'm not showing you the beginning of the weaving!) I practiced several inches of tabby (plain) weave and dealing with things like the selvedges (managing them is, for me, different than on the rigid heddle--or, at least different enough that I'm having to play with it), and crossed warp thread (note to self: double-check for crossed threads BEFORE you start weaving---oh, did I mention that before???) Then I tried twill weave. I like it.
The yarn I'm using is a little stretchy but it's working OK--probably good for me to learn how to do it. I do like the rhythm of treadle-shuttle-beat-treadle-shuttle-beat, which you can't do with a rigid heddle. And having 4 shafts make it easy to do patterns that look complicated.
