I made a 5 layer slashed flannel quilt. When I washed it I got tons of lint all over the back(unslashed) of the quilt. My sister said I should have alternated the flannel layers at 90 degrees. Any tips? This is the first time I have tried thisl. I've gone thru 2 lint rollers trying to clean it up. The quilt looks like it's made of old flannel now.
