Here's a new way to knit in the round: addi FlexiFlips! Your stitches are distributed on two needles while you use the third to knit, resulting in only two needle changes per round.
Each Bamboo needle has a rounded tip on each end and a grippy surface. The Bamboo needles are approximately 3.75" long, with a 2" flexible cable connecting them. The Bamboo XL tips are approximately 5" long, with a 2" long flexible cable connecting them.
