It is a Vermont Designs pattern, number 166. You can see the photo on their website. www.vermontfiberdesigns.com. It’s the top down half zip pullover. I purchased it, so I can’t forward you a link. I’ll type up what they say about shaping…
"Each pair of markers marks a 3 st wide raglan shaping column, which separates the sleeves from the front and back. All increases are worked on either side of the markers, not within the markers.
Raglan leave shaping will be worked at slightly different rates from raglan front nd back shaping. Shaping instructions for each section are given sepeartely in the Chart, but all sections are worked at the same time. Working front, sleeve, and back shaping at the same time, work the number of Every Row/Rnd increases shown, then the number of Every Other Row/Rnd increases, then the number of Every 4 Rows/Rnds increases. You should finish the back, front, and sleeve shaping at the same time.
Specific increases are used for working on the right or left side of the raglan column, and on the RS or WS row. Note that sometimes you will work an increase on both sides of the raglan column, and sometimes on only one side or the other, depending on which sections you are shaping on that row.
Does this help you to help me? Thank you !
