I have been having trouble reading Jean Greenhowes pattern for three wise men. I am an amateur knitter but have had a brain injury so can get confused. I am knitting the basic sleeves. After G-st two rows it say beginning with a K row, continue in st-st but then says decrease at each end of NEXT row… Is the first decrease on the knit or purl side? Sounds like purl side but wouldn’t normally be.
