I need to make a string for my son's bow that is getting ready. I'm using linen thread and looking at a 3-strand Flemish twist string (bow will be about 10lbs and the thread's breaking strain is 26lbs). We'll be making the string together at a Tudor farm on Sunday and I want to make one of the threads a different colour so it looks nice and keeps him occupied for longer - he's 3 years old. I was thinking to use charcoal to make it black to contrast the unbleached linen - is there any reason why this would be stupid for this particular scenario? That is, one strand would be enough to shoot the bow so rubbing a bit of grit into one of the two redundant strands shouldn't be so bad. Otherwise has anyone got any ideas of dyeing substrates available on a Tudor farm that produce a strong dark colour?
Thanks in advance!
