This one-of-a kind chef’s apron is made with a coffee bean sack and gray plaid fabric. The burlap is lined with a smooth woven fabric for comfort. The waistband includes a loop for holding the chef’s favorite utensil and a loop for a dish / tea towel.

I love that towel loop, and an apron like this would cozy up a kitchen in no time!
