Haven't sewn for myself in months

I picked up my GFD muslin, actually sewed the seams (they'd just been pinned), tried it on, and made a few tweaks - and I think it might be basically good. It was already most of the way there, I just confirmed that the marks for the opening were correct on the left front, took a teeny dart in the armscye, and snipped the back of the neck as it was too high. I need to do a muslin for the sleeve as well, but that should be fairly simple, fingers crossed.

Can't decide if I should do this in linen, as it's cheaper and I find the first version I make of anything is often still kind of a mock-up, or tropical wool, as it'll last longer and probably be more supportive (and is more accurate). And of course the long sleeves vs. short sleeves with pin-ons question ...

Inspired to get on with it after wishing I could be involved with the local SCA the other day. I'm sure I could reach out to them and, once people are allowed to meet up again etc., borrow from the beginner's box, but I'd like to get started on my own.
