I've got a bunch of old square quart glass milk bottles that have different dairy names and logos on them. I've been trying to come up with a way of storing various dried grains, beans etc. along the back of the countertop so as not to have to deal with big plastic bags everytime I cook. I was thinking that the milk bottles would do the trick and look cool besides, but I don't know where to find caps for the bottles nowadays. I remember that the milk came with a slightly reuseable foil/paper cap that had a little cardboard disk in the middle and that the little disks became somewhat collectable. We used to pull off the foil cap and use a reuseable plastic cover that you could get at the dollar stores. Anyone have any ideas about how to cap the bottles for my intended use?
