2011 marks the 100th anniversary of the founding of the International Association of Chemical Societies as well as the 100th anniversary of the Nobel Prize award to Madame Marie Curie.

Hexie quilt calculator.... need size of hexie you are using (length of ONE EDGE) and the approximate dimensions you want the quilt to be. It will tell you the number you need (including the 1/2 hexies) and the ACTUAL size your quilt would be. [BTW: my Queen with 1" hexies is about 4350 plus some 1/2s.]
