First Weaving project

I finally got a chance to start weaving last night. Yesterday I finished up the crochet hook holder and the baby blanket. I had my calculations ready for the warping and I was mentally ready to get started.

I sure am getting a lot of practice warping...The first 2 times I had to take apart my warp and rewind the yarn into balls because one of the pegs was loose and my tension was way too tight. I loosened up a bit for the 3rd try. When I was almost done with the first ball I counted the number of ends and I was already beyond my calculated number of ends. The problem is I had calculated that it would take me 1.5 balls of this yarn. I then proceeded to smack myself on the head. I used a different yarn initially to mark out my path. This yarn I cut to be roughly 2.33 yards, and then I proceeded to wrap for the entire circuit of the path. The thing is, each END is supposed to be 2.33 yards. My first 3 attempts at warping were actually producing ends that were roughly 1.16 yards long, half of what I needed. No wonder one ball was more than enough.

For my 4th attempt, I took a second ball, wound it on the ball winder, then joined it to the first ball (still sitting on the warping board) with a weaver's knot and finished winding the 2 into 1 ball. I will probably have to fine a better solution to join ends for warping, but a weaver's knot is tight and I don't think conventional knitting joins (spit slicing, Russian join) would hold up to the tension. I am now almost done warping, with 126 out of a needed 144 ends on the warping board.
