Since I string infrequently, maybe once a month, I kind of have to relearn stuff each time, at least to a point. I like the Parnell knot, I've watched the videos and diagrams, and I'm pretty sure I know how to do it, but: sometimes when I'm tightening it I feel like I just have a half-hitch around the anchor string with no real relationship to the other loop I'm pulling on, and I think it looks weird, and I do it over a half-dozen times and go look at a diagram, and worry about having the string clamped too long, and finally just tie one and pull it tight and it seems OK. I just reviewed a short video of Irvin's where he points out that the Parnell knot is really just an overhand knot, so maybe I'm not crazy? It seems difficult to make sure the part of the string being tied off that's "outside" the racket--like from the last string to the tie-off hole--is tight. I don't want to leave more slack there than I have to, but trying to pull that tight while tightening the knot was mostly what made me think my Parnell knot was wacky. Probably nobody else ever has a problem with this.
