Luckily for me, when it comes to little things, they are PWEs, and within are huge things, in regard to my collection. It's really amazing what you can stuff in a PWE and for the most part, arrive safely. If you package them right, you can ship a myriad of things.
Like vintage minis, and throwback vintage-y cards, like this group from Pat over at Hot Corner Cards.
Or new releases with a relic, like this group from Jeff at Wish They Still Came With Bubblegum.
You can ship some custom binder needs, like a sweet double play-like vintage or a shiny DP card.
Or team set needs and swell miscuts, the last two images courtesy of Jim at GCRL.
I let my wife have her cooking channels, dress shows, families that need birth control and the rest. I'll take my little room with my 2x3 cards all neatly sorted in rows and pages.
