First, I am so excited to be a student here. Learned more I 2 weeks that I have in years of trying to teach myself. It didn't take me long to see that in counting the charcoal warp threads I have 12 not 10. I want to correct this and take 2 out, rethread and begin again. I think the only option I have is to cut the warp, pull the 2 threads off and redress it correctly. Is that the only option ? Second I have retied the bout on the right several times and it is still mailing at me. I might as well correct it when I fix the warp thread count. I will try to figure out how to post a picture next.
You are on the right path - cut out your 2 extra threads and rethread and dent to get the right threading and count fir each section. You can just leave those 2 threads hanging off the back beam - checking them occasionally to make sure they are not getting tangled with the rest.
