I highly recommend using quiltpatis - plastic hexagon templates made by Pati Shambaugh - she is awesome and very helpful with any questions. It is best to order on the phone - have ordered from her several times and I can say she's highly reputable, helpful with any questions whether or not you are buying. Her phone number is 614-443-9988. One of these days, I'll have to post my Grandmother's flower garden I've been piecing since 2009 with 1930's reproduction fabrics.
