I think I need advice....I have a project on the loom that has 1" dents, every couple of inches. For a lacy shawl. I want to add a new warp to fill in where I had dents. So it is not a small section, but evenly spaced across the 21" project. A total of 100 ends to add.
I think I know what to do for threading, but how to I weight all these new threads?
