A man’s boatneck sweater knitted in stocking stitch.
3 colour stripes are knitted in a textured cotton yarn.

All sizes use 1 ball of col. C, 7 balls of col B and 3 balls of col. A except largest size which uses 4 balls of col. A

Pattern appears to have been published by the Style sewing pattern company which is odd. I can’t see any other patterns from them on Ravelry.
