The small one is Ralph Loren no less, not too shabby eh? Almost too good to cut up. Alas it's a kid's size 8-10 and since I don't have any kids and it pretty much fitted a 12x16 pillow straight off, I decided to make it into a pillow cover after all.
I turned it inside out, snipped off the arms and sewed from the arm seam straight down on each side and across the neck (as per the black lines on pic), leaving the bottom open.
There wasn't enough body left to make a fold over enveloped style flap so I got 3 large buttons and used the piping from the sleeves to make loops for the buttons - looks a little scruffy on the inside but fine on the outside - maybe I can get away with calling it 'rustic'
Buttons on, pillow in, finished. I like how you can still see the neckline! No mistaking this was previously a jumper!
