When I first starting making quilts, I would just throw all my fabric in the washing machine when I pre-washed. I wouldn’t do anything to prepare it, and when I got it out of the washing machine, half of it was unraveled and I’d have a bunch of wet strings where my pretty fabric had once been. It didn’t phase me too much, I would just order extra fabric and cut off the strings. (Can we say wasteful, much?)
I finally decided that I should do something about all those yucky little strings, so I started doing a zigzag stitch across the raw edges before washing.
It’s super easy and only takes a couple of minutes to do.
First, if you’re zigzagging as part of the pre-washing process, you should know that you only need to stitch around the raw edges. You can stitch around the selvedge, but there’s no real need for you to do so. If you can’t tell the difference between the selvedge and the raw edges, look closely and you can probably see some tiny little threads already unraveling from the raw edges. You shouldn’t see any unraveling on the selvedge.
