I was watching a Kaye Woods episode and she had a tip on washing big yardage (up to 15 yards) without it getting roped up in the wash.
You are suppose to open it up so the fabric is its full width then accordian fold it down the yardage so when you're done it's all kind of stacked up on itself about 12" wide I guess. Then using lots of safety pins, pin in the selvedge areas on both sides then wash it.
I don't understand how the snip the corners are suppose to work. I've never done it - but then I've also never done this Kaye Woods suggestion. I'm planning to try it out this week. I've got some yardage to wash
