Yikes... I am such a dork.... our local organic health food store is called the Good Food Store.... let your fingers do the walking and call around for the buckwheat. I paid $2.30 a pound a few weeks ago and I use approx 2 pounds in each one. I just use 10 inch flannel squares and sew 3 sides and then part of the 4th, turn it right side out and fill the 'bag' approx 2/3 full. OH, AND DON'T LET THEM SELL YOU THE BUCKWHEAT HULLS..... NOT THE SAME THING....
