DIY Potato-Stamped Reusable Lunch Sacks

by Kelly Lanza

For kids heading back to school, these reusable lunch sacks are an eco-friendly alternative to the typical brown paper bags. The best part is, they can customize these bags using potato stamps! Adults can carve shapes, letters and other designs into potatoes and then let the kids decorate their lunch sacks however they choose.

To make this project, you will need:

  • Reusable cotton lunch sacks
  • Potatoes
  • Small sharp knife
  • Cookie cutters (optional)
  • Fabric-safe paint
  • Paintbrushes
  • Scrap cardboard/cardstock

Begin by cutting a potato in half. To make your stamps with a cookie cutter, carefully push your cookie cutter into the potato, about a quarter inch in. If you’re using a letter or number cookie cutter, be sure to make your stamp backwards so that it appears the correct way when stamped. You can also make stamps by carving a design into the potato using a small knife.

To remove the extra potato around the cookie cutter indent, carefully cut into the side of the potato with a knife until you reach the indent. Remove the piece and continue around the other edges of your shape until all of the excess potato is removed.

To make a simple square or triangle shape, place your potato half face down on a cutting board and trim off the edges until you have your desired shape on the flat side.

Insert a scrap piece of cardboard or cardstock into the lunch bag. Grab your stamp and use a paintbrush to coat a thin, even layer of paint onto it. Younger children can simply dip the stamp in a bowl of paint.

Firmly press your stamp onto the lunch sack and lift off carefully.

If necessary, use a small paintbrush and a bit of paint to touch up the shapes.

Repeat the stamping process until your design is complete. Check the paint bottle for the approximate drying time of the fabric paint. When it’s dry, your reusable lunch sack is ready to be packed with yummy lunch treats.
