When buying bread, look at the twist tie and it will tell you how old it is ... Each day has a different color, as follows: Monday = Blue, Tuesday = Green, Thursday = Red, Friday = White, Saturday = Yellow
When buying produce, be sure to use the ties the store provides. These work great for tying things together, wires, food bags, etc. I can always find a use for them.
When doing a craft that uses short lengths of fine wire and you happen to run out, you can use the wire in the twist ties.
