Now which hook was I using...

Had a very exciting arrival of a lot of Mirasol Cotanani (as well as more Sirdar Peru for the dyeing experiments), which I am making into a yoked cardigan. The problem? I started the yoke, ran out of yarn, put it down with hook. Hook became unattached. I have now picked it up a week later and am trying to work out which hook I was using! I'm making it up as I go along, so don't have a handy pattern to check from. At the moment, I think I was using a 4.5mm - I remember thinking that the hook was smaller than last time I made a yoked cardigan...but I'm not sure. I've been working on various projects with a 5mm hook this week, so the 4.5 feels weird in my hands. I've worked and reworked the same row with different sized hooks, but I honestly cannot see a difference between the 4.5mm and 5mm...so am going with my instinct!

Now some yarn:

This one is mainly black cherry kool-aid, with the end of ghoul-aid mixed in. There is some variation between the pinks, but it's a little too late to take pictures so the nuances don't quite show up.
