Top #6 is worked from the top down, in a brioche tuck stitch pattern - a mix of knit- and purl stitches and brioche stitches.
The neckline is shaped to lower the front, and yoke increasing is a raglan/saddle shoulder combination.
Edges are worked in a second brioche tuck stitch pattern, a ‘broken’ rib with multiple yarn overs.
Top #6 can be worked using up to 8 colors: 1 MC + 1 CC for the body, 1 MC + 1 CC for each of the edges (bottom edge, sleeves, neckline)
For the top shown I used Sandnes Alpakka Silke, using 4 colors.

Finished circumference: 38.2(41.3)44.9(49.6)53.9” / 97(105)114(126)137 cm.
