If the squares measure 10 1/2"before sewing together,the chart shows you'll need 111 blocks.If your squares will be 9" before sewing together, you'll need more. I like to make enough blocks to measure by putting a row on the bed from top to bottom, then across.Write it all down.Remember, you lose 1/2" from each block when sewn together.You'll also lose from quilting the quilt.A lot depends on how much drop you want on the sides,if any.
