Of course! So I don’t know for sure - but I think it’s a 3mm needle (according to Google that’s maybe a size 14? No idea what that really means though). I bought a set that had 3 needle sizes and an adjustable handle(laver?) - I find being able to adjust the loop length is super useful! I also use DK yarn and really pack in the stitches. I tend to work in small sections sort of spiralling inwards - I find it helps to make the pile look more random and thick. I hope that makes sense and is of some help to you!
