Borked I can do fairly quickly,.. twinked might require a longer session.
I'd let you know the next time I get into the BC interior to teach but it's probably still too far away for you.
I will have to mess up my Pfaff again because I wasn't able to make my vintage machines misbehave enough last time when I was doing the tension posts on my blog. I tried and tried and that 15-90 just wouldn't make a nest. I got a "slightly sloppy" stitch at its loosest and snapped the thread once it got too tight. Between those, I had a fairly acceptable stitch most of the time. After those posts, I had to disassemble and adjust the Pfaff's hook retaining finger thanks to the mess I made.
