Used this fabric in navy
https://ukfabricsonline.com/high-quality-softshell to make this pattern up. I'm reasonably pleased with the result, it'll be great for dog walking and it's very light and hopefully not warm - I get so hot!
I tried sewing with a microtex needle to start with, but it wasn't having it, so tried a universal and it work reasonably well although there was the occasional skipped stitch. There were lots of skipped stitches on single thicknesses eg stay stitching the neck edge.
I don't know why it seems to be "dragging" down at the front from the poppers (kam snaps, another thing I've discovered recently!), but maybe that'll disappear with wearing.
(Note to self, for heaven's sake, stand up straight and shoulders back for photos!!)
