@daniel_bohrer The first buttonholer I bought for my Singer 301 cost more than the machine (which came from a thrift store). This was pre-eBay, so I had to get the buttonholer at a local specialty shop that sold vintage parts *and* had the slant-needle version. Now I see them all over the place, and they're usually $10-$20--not a bad price for a bit of vintage wizardry. :-)
