Storing items in garage attic

[mspicer1234]

I was considering storing items in the garage attic like folding camping chairs, artificial Christmas wreaths and outside decorations. I know it will get very hot in the attic and I should only store items that won’t melt or be adversely affected by the heat. Currently the only venting in the attic is the eve soffits and roof ridge vent.

For those of you that store items in your garage attic what items have you been able to store without ruining them?
