Ophicleide is a top-down knitted cardigan with three sleeve options (puffed cap, short and 3/4 length).
The stitch pattern of this cardigan utilizes stretched stitches. The herringbone part of the pattern uses stretched stitches crossed over regular ones. In the honeycomb pattern stretched stitches gather the garment gently to form those shapes. Neck opening utilizes short rows for subtle shaping. Neck opening and sleeves are finished with i-cord bordering. And that’s about it about special techniques needed with this pattern (well, you could check out some temporary cast on method’s too, if you are not familiar with them yet).
A nice fact to know before you decide to start is that finishing job (read sewing) is pretty much minimized in this pattern: you just attach short sections of i-cord border to the yoke area of the front pieces, attach few loops and hooks to the border and probably finish the sleeve-underarm area and i-cord ends of the sleeves with few sewn stitches.
