This is a pattern for a top down circular yoke cardigan with some Raglan shaping. Wish Tree is intended for the experienced knitter, comfortable with reading partial charts; patterning is worked over the entire cardigan and includes (single-colour) folded hems.

Stitches are cast on (provisionally) for the neckline, then short rows are worked for neck shaping between colourwork motif. Once the yoke is worked, sleeve stitches are separated from body stitches. Underarm stitches are cast on/picked up and each element is worked separately to folded hems.
Once the cardigan is worked, the steek is prepared and cut. Then each button band and collar are worked.
