Maybe Nick's share could be covered by his "sweat equity". Just throwing that out there.....So we split the cost of one yard between 3 + Labor?
It takes about 3 hours to make a tie, I would request $30 labour for each tie. That covers the time and other materials needed besides the silk (thread and tie interfacing).
I would suggest an initial limited run, perhaps pick a silk, three people to cover the cost (one would be me for the first), I would purchase the silk and have it sent to my address and make up the ties. After this to make sure it runs smoothly, we could organize a larger list and figure out who wants what tie in what silk.
Given that DamianM first brought this up, I'll defer to him and suggest the first one be #13. It isn't the one I would choose for myself, though. Anyone else who likes #13, message here or PM me. If more than three are interested, we can get more yardage at the same time.
