This is a pattern for a cardigan worked from the top down and in the round, with a circular yoke, a steek, and using the Fair-Isle colourwork technique.

Please see schematic for all approximate finished sizes. Plötulopi is not usually worn against the skin and you may wish to work a size or two up from your actual measurements. Feel free to make any adjustments, as needed, for best fit.
