Since I buy all my fabric secondhand, I have a real problem with seeing potential in everything and then never wanting to use any of it as “test” fabric. Both of these fabrics were in that slot - not patterns/colors I’d wear out, but too high quality to “waste” as muslin fabric. But combined with the Simplicity 9250 pattern I got from @MamaRhi in the Use it or Lose it last year, they make great spring pajamas!
