OK, I STAND CORRECTED..LOL...IT IS IN FACT THE "YIN YANG" PATTERN BY LEE FOWLER... I GOOGLED ENOUGH UNTIL I FOUND IT. THE ONE YOUR MOTHER MADE IS SO MUCH MORE BEAUTIFUL...THERE IS NO PATTERN AVAILABLE ON HER WEB SITE,, JUST THE QUILTERS CAMP WHERE SHE TEACHES THIS PATTERN IN A CLASS...HOPEFULLY SHE WILL DO A PATTERN SOON...LET US KNOW IF YOU CONTACT HER AND WHAT HER RESPONSE IS...THANKS
