Need Spinning Help!

Okay, ignore the rejected paint color that we haven't finished painting over and the cheap trailer door! I would like you to look at my spinning. This is 3-ply Navajo plied Corriedale (my friend Cary's ewe Valerie) which was nice to spin. I am still having beginning difficulties. I had problems with my singles getting it spun enough and then when I plied I think I overspun it...my feet get too happy! I treadle too fast. I haven't washed or weighted this yet. Is there any hope of this being "knitable"? I have enough of this to spin to do a sweater and this was "trial" to see what I could come up with. I think I will put the plying head on next time and be more watchful of my treadling.
