Hehehe...ok. We're going toooo far on these bobbins. I'm sorry, Ironraven. When I said "dime" sized, I wasn't looking at one... I was in here "remembering" one. They're a little bit bigger than that.

My wife brought the package in here and there are three left in a package of five. They are: "J&P Coats (brand); N.417; Model 15 Bobbins". The price tag says $1.04 but it looks like it could be 10 years old. Now, I'm measuring one of these little bobbins. 15/16"

Sorry about the confusion. They still fit just fine in the PSK.
