When I visited my first grandchild as a baby, she was often wrapped in a very interesting blanket. It had been knit for my son-in-law by a family friend, whom they fondly referred to as Aunt Tilly. I spent the next few years searching for the pattern to this circular blanket. I knew it was not Elizabeth Zimmermann's Pi Shawl because it was NOT knit in the round, but in rows. You may think that you would never knit a circular shawl in rows but there is a reason to at least consider this pattern. If the blanket is knit in rows, it can be entirely knit in garter stitch - no purling! Personally, I don't care for a blanket or afghan pattern that has a "wrong" side. Knitting a blanket in garter stitch takes care of that problem. When the coming of the second grandchild was announced I went into overdrive trying to find Aunt Tilly's pattern but finally had to take the original blanket of my son-in-law's and stitch by stitch write down the instructions:
