If by jelly jars, you mean canning jars(my mom did a lot of canning, including jelly), I do believe I remember my mother using them as drinking glasses (or maybe it was my grandmother). Anyway, I remember seeing these jars in the garage with nails/screws in them and also using them to keep bugs or some kind in them, pokig a couple airholes in the top. I laugh as I say this because I am sno NOT a nature girl now that I'd even consider catching bugs.
