I would use wax paper

I live in texas and today it is 105 degrees. I would be afraid of wax paper melting or rubbing off.

This is a good question! My guess will be to store them in an airtight container eg; Tupperware or those deep-freeze plastic bags that you can zip-lock.

I keep mine stored in the zip lock bags. If it's small I put n sandwich bag then put a lot of the small individuals n their bags in a large zip lock. they were all fine when I got them out this past christmas. If they r not 3 dementional I keep them stored flat. I also like to use boxes that r used to store photos n so they r non-acid. *

I put them in a zip lock bag. I have several in one bag. I DO keep them in the house where the air conditioner is running to cut down on the moisture. Most of my Christmas stuff is in the barn, but not my fsl orns!

Thank you all for the suggestions, now to make even more!

To also keep moisture away from the inside bags, etc. I never throw away the little silicone bags you get in shoe boxes & other items you buy. Place one of them in with the ornaments to help absorb any moisture that may happen to find it's way into the containers.

Zip lock bags work well for me. Most of mine are white so I just stack them. I do separate the colors.
