Yes, I looked at that page, and can eliminate some of the things listed there as issues. My bobbins are not catching or giving me grief, my sequence is good, and I'm not weaving close to the beater... though I wonder if I could be weaving too far from it?
I could spend some more time looking at what I'm doing differently with my two hands, for sure. I might have legitimate tension problems, because I had a difficult time with my warp---but it seems pretty evenly tensioned to me at this point.
I think one thing I'm feeling unsure about is what exactly this problem is, so that I can solve for what's causing the problem, if that makes sense. Could this be too little draw-in? I don't see loops on the selvedges, just that downturn in the weft.
