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.

I bought myself a barbie Knitting machine via Amazon UK because it was cheaper than the more professional looking ones. It works fine for the circular knit but is very messy at the edges when it comes to trying to knit a flat piece.
