and since I use canning jars I can use my vacuum sealer to seal them. This helps to extend freshness. I use ½ gallon canning jars for the back roll on my tiered shelf, then quart, then pint, then half pint. Put the labels high and you can immediately see where everything is (photos will be posted soon on my blog). For things I use on a daily basis I will use “recycled” jars, such as mayonnaise, pickle etc.
