I found a pretty lilac cotton at Jomar, but it's not very hefty, which I think a habit needs, so I was advised to at least interline the front pieces with something mid-heavy weight. I have a cotton canvas remnant, so it should be enough to do that. It'll be lined in beige linen. I spent 4x as much on the lining because I got sucked into having a historically accurate lining fabric. I'm silly sometimes!
For the pattern, I heard the Mill Farm pattern was pretty good, so I'm going to try that.
I washed and ironed all the fabric, and I've cut almost everything out, so I need to get sewing!
