They come in different shapes and sizes from a tiny 4 ounces up to a quart. (And if you ever see a 2 quart size, grab it - they're a rare find in this age of smaller families.) They're simple and classic and reusable. They're practical and have an air of elegance at the same time. A shelf of canning jars reminds me of the wife of noble character in Proverbs 31.
The jar in the photo is a sewing kit from Anthropologie, not thrifty by my definition, but inspirational, don't you agree? (Going in their stores is like spending time in an art gallery!) I think you'll find the links below may better earn the "thrifty" label. Also, be sure to do some design review with Lucy's post on making your jars more beautiful.
