Agreed. I'm thinking: The weight! The weight! Peg board is not the sturdiest stuff in the world! Pretty, sure, but IMO not terribly practical over the long term.
My big issue is that I don't have a place with stable temps. I find that when my filled jars have big temp fluctuation, the lids are always plinking. The seals never break, but this is worrisome to me. I'm now storing them in my "office" against the wall which is furthest from the heat source (usually wood stove, but the office also has a duct from forced air furnace. I keep that vent closed and covered.) Much less plinking in this location.
Since I'm always collecting empty jars for future canning efforts, I do have lots of extras to store. Always on the look out for boxes from the grocer to recycle for jar storage. When a jar goes into storage, I try to always have a lid or plastic over it so it doesn't get dusty inside.
I recycle my lids, and recycle jars and lids from the grocery store. Lids get carefully washed and stored for next use. I place an extra layer of protection over the lid when I open it wo the can opener doesn't ding it. My son bought me a set of Tattlers to trial. Looking forward to using those.
