With assistance from Barb I very quickly strode from one end of the store to the other, searching for perfect wheat/cream fillers (among other things).
The woman cutting my material asked me that fateful question, "How much do you want of each?" I replied that since I had to buy a half yard as a minimum, then...I guess a half yard of each would do.
"No," she said, "you only need to buy at least a half yard of the sale fabrics, but you can get however much you want of everything else."
Well, huh. I guess that last clerk I had wait on me wanted to keep it simple, because she told me I had to get no less than one half yard, no matter what it was - and my choices weren't all on sale!
So there you go. Be certain as you're checking out that your clerk registers you in their database and then hands you a savings club card. After you have purchased so much, it is worth a great discount. Stop by and get the details - you'll be glad you did!
