What is the best way to store TS jigs? ("store" as in I won't need it today, not "store" as in the "U-STOR-IT type commercial places)
I live in a low humidity climate; RH is rarely above 40%.
Eventually I want to climate control the "gara-shop" but currently the shop RH is whatever outdoor RH is.

The several jigs are DIY (WIP), not store bought.

Bases are all 3/4" birch ply.
Largest jig (taper) measures 12 x 34
Next larger one is 14 x18....Smaller ones after that

Should they be stored on edge? Hung vertically? Flat? Doesn't matter?
Thanks
