Back when I first started hosting scrapbook workshops, my customers were often squished around my kitchen table. One night, a customer asked to use the star pattern from my custom cutting system. I handed it over and she proceeded to cut her shape out of her paper and leave a permanent star etched in my kitchen table!! Oops, she forgot to use her cutting mat!!!
Luckily, with time and lots of day to day abuse by my children, the etch has worn away and can only be found if you really look for it!
