First you will need to procure a vintage 1956 Fender Strat complete with original tweed case. They are available, just check out eBay.
Remove the neck, then sand the body down to the bare wood. Nice lookin' wood, huh? Don't forget to sand the headstock and neck to get out those darn aged-in finger marks.
Next, get a couple cans of Shell Pink spray paint. Krylon® glossy ought to do the trick. Hang the body up and spray it until it looks good.
Put it together and what have you got? Hello Kitty! And it looks great!
By the way, it's April Fools Day!
