I had made some of these the other day for single loafs using pants legs, but we buy 4 loaves of bread at a time from the outlet so that wasn't gonna work for us.
I made this version using a vintage pillowcase and 4 soda cases and we used it today. The strap is the top hem of a vintage sheet.
My 4 year old carried the bread to the car from the store and into the house today and it's still UNCRUSHED! YAY!
ETA- the cashier at the bread store loved the bag!
