Worked up a flannel caftan, too. Just the basic: Sew the side seams (don’t forget to leave arm holes, like I did!), finish the 4 sides of the 2 pieces of fabric (cut to whatever length you want), decide which neckline to fool with (boat neck – sew straight across & leave a hole big enough for your head – don’t forget!). Easy peasy. Photo after I’ve put the ironing board back together & given it a pressing!
