Bullseye!
Last year, when Josh visited the Buckland (MA) Historical Society's Wilder Homestead restoration project, somebody mentioned needing glass panes for the new door transoms. Ever helpful, Josh piped up: "Hey, I could make some!"
Ahahaha, he did it again! After agreeing to make "a few" hand-blown window panes that would replicate the historical panes, Josh discovered that this meant not a few, but 32 (with a few extra to spare, just in case). Eeep. Well... okay then! Off he went to the hotshop to make 36 bullseye glass panes precisely the way they would have been made back when that barn was constructed in 1798.
