1.00 mm Prym/Lacis cro-hook

I have the Annies Attic hook and also recently ordered another 1mm and 1.5mm and 2mm Prym hooks from the bottom of the page here. I was happy to have the larger sizes because I’m using DMC Petra 5. Imagine my surprise to find out I was using the 1mm, by mistake. It is a little hard to get all the DMC 5 into the hook without splitting it, so mad at myself for not using one of the medium size hooks. 2mm would be too large for this, and should be used on DMC 3 or other 3 thread.
