PiobBear - got excited about that badge until I saw it has the same cotter key back as the original...dang.

Maybe its time to look at headwear and the saftey pin option.
Another alternative to perforating your apron would be to mount the badge on a plain belt buckle; not hard to do if you're handy, or you could take it to a jewler. Personally, I wouldn't use a blanket pin; they're made for very heavy weight fabric, are nearly as big 'round as pencils, and serve no practical purpose at all.
