Splicing a Broken Warp Thread

A short weaving video, showing what happens when weaving Harrisville Designs Highland weight wool, and suddenly a warp thread breaks. It has to be fixed by splicing in another warp thread to continue weaving.
I know that the colors don't match, but I also know that with this woolen warp, after the scarf has been fulled (wet finished), no one will be able to see the splice.
