I like KLL and KRL increases too. I'm not sure how they work on the purl side. I subbed them for KFB in a bunny pattern and today I was informed that it's OMG cute and needs to become the Monty Python Killer Rabbit so I guess fangs are in its future. Kids are bad enough and then there are the grands. LOL Just think what I'd have if they were Aussies to boot! I understand you're a strong-minded, independent lot.
The first time I heard Unix I thought they'd said eunuchs. Was I ever glad I didn't open my big mouth.
I like KLL and KRL increases, too, I often just sub KFB for the ease of it though.
When asking questions ALWAYS post the name and a link for the pattern if you have it.
