Activity for Katie

Finally married and worked through a COVID wedding. You can see in the 2nd picture how we spread out the ceremony seating. Kept everything outside, handed out masks to those that wanted them and handsanitizer to everyone.

I am wanting to do straw bales for my ceremony seating. I'm wondering if anyone has any ideas on how to keep the fabric pinned down like in the picture. Any other tips for this kind of seating?
