Yes, that was probably set for Ultracote, however, if I suddenly found myself using MK, I wouldn't change anything. I would start with the iron as is,, and increase or decrease the heat as needed.

I sould also mention that I do not use the iron for shrinking - only ironing. I use the heat gun for shrinking.

And yes, MK HAS changed over the years - something to do with killing rats in California. [:@]
