flattening plywood in the cold?
i ordered a sheet of 3/4" plywood to build a toy storage unit for my kid's toys. when i ordered it back in November or so, it was part of an order for work and the plywood has been in the garage there since then. i noticed the other day that the sheet is slightly bowed and thought i could just keep it there to use for other rough basement projects and pick up a new sheet. i'm wondering, though, how hard it is to flatten it outside in the cold. i'd bring it down in the basement, but we're picking up work and space is limited and will be worse as we move along. has anyone tried this in a New England winter? i guess i could wait til it warms up but then i assume the cup will be worse then. any advice? thanks!
