I used to knit a bit, quite basic but haven't now for about 15 years. Want to start again and I noticed that lots of people now use circular knitting needles. Would like to start with a basic DK cowl (in the style of the recent one Sandra aka Cherry Heart showed on her podcast) as I presume there would not be a beginning and end and therefore no sewing up/joining would be necessary. Is this correct? Can anyone recommend a type/brand of circular knitting needles please?
