Looking for opinions and creative help

[veleno45]

As my collection grows I have had problems figuring out how to store my graded cards in a way that is acceptable to me, and more importantly, my wife. I was advised that plastic protectors, cardboard boxes, sleeves, etc are no longer acceptable on the dining room table. Since I have not been able to find any real quality that is out there, and haven't seen any good suggestions here, I reached out to my Amish friends to build a better cabinet/flat file specifically for my graded cards that will blend with the furniture in my house. Here is where I need your creative opinions and your knowledge. I thank everyone who answers my questions. Your help is appreciated.

1) I only own PSA graded cards right now so I lack slab knowledge. Are all the major grading companies slabs exactly the same size and weights?

2) Do all the cards need to be upright, or would you rather have them on their back, flat? Is on their side ok? Consider access to the cards also please.

3) Do the drawers need to be felt or fabric lined, or is straight wood ok?

4) How many cards would you expect a single piece of furniture to hold to be effective? Keep in mind this is really for personal collection, not dealer storage and such.

5) If you were custom building this what would you like to see on this piece that I am missing or haven't thought about?

Thanks!
