I will bring a bag of white cotton balls, Nancy.

I also picked up two white bendable "cardboard" sheets from Sam's Club today. They are used as dividers between stacks of boxed product - about double the size of a poster board but not quite as stiff. We may need one for a game (cornhole?) scoreboard and you are welcome to the other if you can use it for crafts or whatever!

Nancy, it may be that I am just a bit crafty.  ;D ;D

Actually, if you ever need big sheets of clean, flat cardboard, Sam's and Costco (probably BJs as well) will allow you to just take them out the door. I used to be the "prop lady" for my old church's Vacation Bible School and used many of the cardboards for backdrops and "buildings."  If you ever need odd pieces of styrofoam (which we did for a "Rome" theme), go to your local furniture store's shipping/receving dept. and ask if they have any on hand or could save some for you with a specified date to return to them.

I've got the cotton balls in my stash already! See you soon.
