I just had to post this because only true vintage machine lovers would appreciate it. I was sewing a quick pillowcase yesterday and stupidly sewed right over a pinhead. The thing was, I didn't even realize it until I went to take the pins out and the head was sewn right into the fabric. It was one of those flat flower shaped pins. I had to use the stitch ripper to get the pin out. I love my 15-91, it will sew through anything and I have the holes in the pinhead to prove it.
