We just built a new attic space over our garage. I have some clothes to store - DD's special dresses, old Halloween costumes, etc. Would it be better to store them in the attic in a Rubbermaid container or in the basement? Our basement is damp, and we did get water once in 10 years but not since we got the new leafguard gutters. Also need to store DD's dolls and Barbie's, she is 8 (sob) and done playing with them. Will the attic heat ruin them?
