Here is my Gedifra Cicco that I am using for my poncho knit-a-long...and here are the circular needles that I just bought (US17) and for some reason I was convinced that I had bought them too short (my pattern calls for 16in. needles), then I told myself that the 40cm must be too small!...I even called the lady at the store...she was like "16in. is 40cm!" I felt sheepish, but still look at how short these things look!
