Rustic baskets & metal buckets for snacks - liners?

What type of food is going in these metal buckets?

I had a hard time finding liners for my metal buckets, but I would suggest looking at garden centers and places that sell flower pots. They usually sell some plastic liners there.

Pretzel/nut mix

I thought about using fabric to make liners for baskets.

You can make them yourself with wrapping paper. Roll it up the same way as you wrap a bundle of flowers, then fold the bottom over, so the top is at the right height. If you want the print visible on both sides, put two pieces back to back.

Very clever @Muriel.

You can use dish towels, napkins, printed or plain parchment paper, etc.
