Cheap Plater dust cover

Hi, As I was eating breakfast this morning I had a neat idea. And I did it and it seems like it will work quite well.
Keeping dust off of my Oracle Delphi's palter mat has always been a big pain. Dust just seems to glue itself to the sorbathene like plater mat.
While eating my 12" pizza for breakfast it came to me that the cardboard that my cheap pizza came on is the same size as if not a hair larger in diameter as my plater. So taking another pizza out of the freezer and removing the still clean cardboard disc under it. I fashioned a cheap plater dust cover.
Well I did have to unwrap a couple to get a completely spotless one. But after I had the clean disc in hand I placed an old LP on it and marked the center for the spindle hole. I then used my only special tool a 5/16" gasket punch and punched in a cental hole that is slight larger than the spindle. Painted it flat black with some spraypaint to give it that hi-end look and let it dry. Thats it I put it on when not playing records and it keeps the dust off. Anf it is practicly free. I am sure just about anyone could make it with little effort.
I know I could use the Oracles dust cover but I don't like the sound with it on. Also many turntables do not have dust covers so have at it people.
