Technology allows businesses to be global operations, and even the smallest business can have clients in every time zone. Different countries and different cultures may have different preferences, however; what sells well in one place may never sell in another place.
Circular knitting or knitting in the round is a form of knitting that creates a seamless tube. When knitting circularly, the knitting is cast on and the circle of stitches is joined. Knitting is worked in rounds (the equivalent of rows in flat knitting) in a spiral. Originally, circular knitting was done using a set of four or five double-pointed needles.
Now you have a twisted circle that appears to be 2 rows, but you have a continuous edge from the first stitch ('F') to the last stitch ('L'). You have just completed the first round. Chain 1 (or number of chains for first stitch of your pattern stitch) and work next round. The scarf is worked in rounds. Because of the half twist, one round results in stitches worked on both sides of the beginning chain. I found that I needed to reverse direction on each round to keep the scarf from curling.
