I have been making these for over 20 years now.

It started because I did not want to throw out one of my favorite 45s that had bad scratches and skips.
(probably from me playing to too much)
SO I cut the part out with the label and stacked a few other pieces on for effect and embellished with some colorful glitter glue you can buy for your glue gun and then I attached a pin back and whaa-la...
My favorite record, that I can keep for ever and enjoy wearing on my blouse or pined to my purse.

I never cut up good, playable records.
(I guess that's the DJ in me.)
Just ones that are warped or badly scratched and really can not be played.
