Gauge square driving me crazy

Ok so I’m participating in my second CAL ever. The Hygge CAL designed by Haak Maar Raak in colab with Scheepjes

I haven’t gotten started with the actual CAL, I haven’t really had the time, and I’m still trying to get the gauge square right. I did one yesterday with the recommended size hook, 4.5mm 

But I wasn’t getting the size right. It’s supposed to be 10x10cm and I ended up 1cm short. 

So today I got a 5mm hook (and a 5.5 just in case) to see if that would do the trick. So no time to waste, rip it up and start over. 

Just finished it 

And one side is 10cm but not the other…aaah!!! 

I’m going to bed now, goodnight!
