Have a lot of jelly jars with lids - what can one do with them ?

Use for display of dried veg and fruit. A variety of peppers looks neat in different shaped jars.

can use lids to put pie crust in and make little individual pies or use for canning

How big are the jars? Do they have writing on them? Let us know. GL.

I make my own sugar scrubs and give them away as gifts with these jars. Here is a basic recipe:

we have a very narrow shelf in our small kitchen. I had bought some lovely jars for this shelf, but then we started getting jam in jars that fit even better. We use these jars for various things; like corn holders, mixed spices and seasonings, nuts of various kinds, small pieces of hardware, anything you use (in our case) in a kitchen and that can best be held in a jar.
