My Pockets are so full where is a safe place that I can stash all my stuff in so it wont be stolen

thanks

In any container. I'd suggest one in an inn.

Me being an Archer and all I stash my junk in my cabin in the Umar Hills. I would advise you to do the same in your "stronghold" ALTHOUGH you can put them in any shelf, table, chest, etc. and it will be there until you come back for it.
