Any words of wisdom or lessons learned you'd care to share about working with vinyl covered cotton? I think that is what I was admiring at LQS Friday. Heavier than the water resistant bright materials, longer lengths like 54 to 65" wide runs about $20-$25 per yard? They had some wonderful aprons and bags made up in it. Would appreciate any advice, do's & don'ts, and tips you'd care to pass along.
