I made a baby quilt with chenille and flannel. I washed both of them several times. The quilt came out great and the grandbaby loves it, but, it was a huge mess to work on and it ended up packed into the bobbin case of my dinky mechanical Brother. I didn't realize this til months later but the machine never skipped a beat. So other than washing it first, do check your machine frequently and clean it out, not doing what I did.
