Ok, I'm pretty new at stringing (well, not really, I just have not done it for 15+ years, so with my new machine I consider myself a newbie) having done 7 frames since receiving my new machine. This morning I was asked a question which I didn't quite know the answer for... I typically do hybrid/2-piece stringing on all my frames, with a starting knot and 3 Parnell knots at the tie-off points. The question I had was: why I'm not using the starting knot as an ending knot as well. I don't quite know the technical reason behind this. I don't know why it is (is not) possible, but can see a benefit of having uniform knots (without starting clamps) and the tie-off knots having a tail closer to the stringbed.
