What I found is that Lizbeth actually works out slightly smaller than DMC Babylo. I also concluded, in this case, that I was enjoying making this with Lizbeth most of all three threads. So Anchor Artiste is biggest, then DMC Babylo, then Lizbeth (all size 20).
Here are all the motifs I've tatted so far…
and my favourite's the cream!
I also tatted one diamond which is the motif that will fill the gap between the round ones. Don't know where I'll get to with this but I'm off to tat a second cream motif.
