Maybe I’m the only one who didn’t know this, but it only just occurred to me to try - and it worked!
I gave it needle size, ply and the garment size I wanted - as well as asking for Australian sizing and instructions (so you’ll need to change that for whatever you’re used to) and from what I could see it was pretty good. Haven’t actually tried it but I may for a small project and see how it goes.
Edit to say that I’m very aware of chatgpts limits (I work in a field where it’s being abused) but thought it was an interesting idea. Simplicity would be key. I’d consider myself a beginner this might be a good way of creating small simple projects. Or nonsense! I have bags of cheap wool that I got through my local buy nothing group so I’m always up for a bit of experimentation.
