Don't worry, its the arrows he's after
As I suggested earlier, I wanted to try some frames in Basswood. these weather really nicely but they are more prone to warping during the process.
So to recap I have tried glazing sandwiched between card frames, ply frames with individual panes, Card frames and individual panes and basswood with individual panes, I'm not sure there is anything else I can try before it is decision time, The difference between card and basswood only really shows under magnification, but despite the difficulties I'm leaning towards basswood.
