Why would either snipping a corner or cutting a square out of the corner eliminate ravelling? Guess I don't get it. The threads at the end of the cut are coming off--that is what is causing the ravelling. Is the square cut out supposed to stop that from happening. Why?
Anyway...just snip off the threads when you take it out of the washer/dryer. It doesn't seem like a big deal to me. One swipe of the rotary cutter and they're gone.
