Alternatives to wood slice centerpieces?

Hello beautiful brides! I have been wracking my brain trying to figure out what I can put under my center pieces that ARENT wood slices.

We are having a rustic/romantic themed barn wedding. My center pieces are going to be mason jars wrapped in burlap and lace with a mix of baby’s breath and various blush and burgundy florals, as well as milk bottles (with the base of the bottles painted gold) with stems of pink wax flowers in them. I’m also using tiny wood slice placecard holders to hold our table numbers, which will be written in calligraphy on little squares of kraft paper.

I was thinking maybe doilies or scrapbook paper, but I’m having a hard time visualizing how to use the scrapbook paper as the base of the centerpiece (mainly because I don’t want to just throw a square of printed paper down and sit my handmade centerpieces on them). Suggestions? I would love to see what you have done with arranging your rustic centerpieces!
