ETA: oh yeah, the reason I came by. My son has been BEGGING me to make him a knight outfit for a month. Every single day. "Have you made my knight outfit yet?" then today he upped his order to be a knight outfit AND a dragon outfit for his twin brother so I he can protect me (the princess, naturally) from the Dragon. Weak plot-point where I made my own nemesis aside, I took him to Joann fabric to pick out his knight fabric. He picked this insanely shiny, thin, nightmare-to-work-with fabric. So I paired it with $3/yard gray felt and the Portrait Peasant pattern to come up with this in about an hour. I spray basted the shiny "Knightmare" fabric to the felt and it was a breeze to work with. I did the shield from felt too, which I added an embroidery design I downloaded for free. I have since added another elastic lower than the shield to make it less dress like.
And what does the knight think? I know you're dying to know. "Um, Mom, where is my shield and my sword and my helmet???"
Sigh.
