Show of hands, boys and girls... Who among us, while attempting to smooth a small bit of metal or whatever, has sanded down your fingerprints so badly that it hurt to hold a pencil? Yeah, me too.
As Ricky Ricardo would say, "You gots some splainin' to do, Lucy." Well, the photo
splains it all but I'll break it down for those who had too much Friday night.

Half-inch medium density fiberboard (MDF) sanding block with some tape - your choice - wrapped around it
sticky side out. A FLAT surface to work on is required. More MDF is good...and it's what I had on hand.
Stick whatever needs to be sanded onto the tape and you're ready to go.
Emery cloth in various grits will reduce thickness quickly. Silicon carbide papers in progressively finer grits will finish up. I've tried using a lubricate on the paper to speed things along but it tends to unstick the part.
No tender fingertips and you can still use a cell phone.
