It varies by the material, climate, area available, etc.. Talk to a
local sailmaker. They can give you advice for your situation.

I've just bought my first boat - a 1983 Ericson 28+ - that came
equipped with several sails that I don't think I'll be using this
season. Right not they're all stuffed in sailbags sitting in my
garage. Is this an acceptable way to store sails that won't be used
for a year? Thanks in advance for any suggestions.
