Desperate: need 1 skein Ballybrae Sky Blue Tweed

I have been knitting this sweater for my Mom for 15 years and I am finally finishing the last sleave and I am going to be short! Does anyone have even the smallest ball of Ballybrae worsted Sky Blue Tweed in their stash? Am desperate.

I found one person on Ravelry with some who is willing to sell or trade.

Ravelry is free to join. Better hurry if you want it!
