Well, here is a pattern I got online of a women's housecoat from 1970
I cut up some pieces out of curtains we had for windows and a closet at our old house. Then I added the bottoms of some Ikea curtains we bought for glass doors we have on our bedroom and bathroom (bathroom - can you believe there was a glass door on the bathroom??!) The curtains were too long, so they got shortened and I finally found a use for those curtain bottoms - see further below.
Partway done. I used the red for the bottom pieces, the side pockets and the inside of the stand-up collar.
Now it's done. Here is me wearing the housecoat. I really, really, really, really, really, really love it!!!
