This sweater is worked in Knitweave technique with Stitchworld pattern 30 (the same as punchcard 1), the simplest of all.

Main yarn: 2ply wool
Weaving yarn: Wollmeise Pure

Garment is worked sideways from sleeve to sleeve throughout. Back and front are worked separately, there are shoulder seams. Main tension: 5 on Brother KH 965.
Welts, cuffs and neckband are made with 2ply wool held double.

It took quite some time to knit this garment because it is more tedious than plain knitting. But the effect is worth the effort, and it is a good way to use, e.g., multicolour yarn if you do not have enough of it to knit a complete sweater.
