There were a bunch of 1980s & 90s patterns boxed up in the attic at the shop when we bought it. None of them have the outer sleeve (envelope) on them. I think the pattern makers used to have shops simply discard the contents and send in the outer sleeve to receive credit for unsold out-of-date patterns. I’m not sure about that, but I think that’s how they did it years ago. I assume that the previous Owner couldn’t bring herself to throw them in the trash, so she boxed them up and stuck them up in the attic.
The patterns are all uncut and contained pretty well wrapped up in the instruction sheets, so I put one complete pattern in the portable case bottoms of machines that I service, partly to catch any excess oil drips, and for perhaps a pleasant surprise if or when the user ever peeks under the machine. It’s just something that I do for fun.
