The WPA is participating at the International Preservation Trades Network in several ways.
Saturday 8:30AM members Bruce Murray and Alison Hardy will be presenting a study of the transition from hand making sash to machine fabricated sash in the context of Philadelphia.
At noon, Elizabeth O'Byrne has organized the next Glaze-A-Palooza where skilled window pros compete to see who can claim the prize as the top putty head (and there are some great prizes!)
