Ok, I said permie, but that was just so I could bang on about stuff!
Anything 'handy' you just can't have enough of?
Do you think some people might think you have a problem...?

A couple of mine are:
Jars and lids. In the 80s my mother taught me that 'nescafe' coffee jar lids fit our standard agee preserving jars after the seal comes off.
My entire life seems to have involved quite a lot of 'does this jar have a lid?'
Rope. Ok, I'll open it up to 'things that tie stuff up': baling twine, chains, Cordyline australis leaves...
I'll leave tools alone

Both of my grandpas were new farmers during the depression, they recycled EVERYTHING. One of my first jobs on the farm was to straighten all the nails they just pulled out so we could re-use them. I learned you could never have too many nails or screws sitting around.

Generally if something needs fabbing up, I can do it so long as we don't run out of:
Cable ties
2.5" deck screws
Recycled baling twine
biner clips

Never throw away:
baling twine
milk jugs
feed bags (although I haven't found a use for them)

Always bring home another:
bucket if you are at the big orange store. Can't get them for free around here, too many people doing serious food storage in competition.

Hi Leila! I'm obsessed with any type of glass container, old pyrex and cast iron cookware. Most of it is in storage, but I continue to collect.
Ooh.... Almost forgot ReBar. I use it throughout the homestead and garden for numerous projects. I usually get rebar scraps at construction sites.
