Wool Sweater Design with AI
For a wool sweater, most mills quote wool knit at 250 to 500 g/m²: a classic pairing.
It is the heaviest of the 7 cloths this guide lists for this cut, ahead of polyester knit.
Next to cotton knit, it is heavier, more fluid, warmer to wear and more demanding to care for.

How wool behaves on a sweater
On a sweater it skims the body without clinging, and gathers at a yoke or a cuff sit softly instead of standing up.
At this length a soft cloth moves gently at the hem and falls in loose folds.
It wears warm, which places it in autumn and winter collections.
The finished piece is usually labelled dry clean only.
It recovers from creases overnight and resists dirt, but it felts if washed hot and moths eat it in storage.
About wool
Wool is the fleece of the sheep: springy, warm even when damp and naturally resistant to odour. Fine merino feels soft against skin, while coarser wools give tweed and melton their body.
Fine merino comes mostly from Australia and New Zealand; Biella in Italy and Yorkshire in England are known for fine worsted cloths.
Wool dresses, skirts and tailoring are usually lined in viscose or cupro so they slide and do not itch.
Cutting, sewing and color
An 80/12 needle; wool shapes with steam, so ease a sleeve head or a curve with the iron rather than with extra seams.
It takes acid dyes evenly, and heathers and marls come from blending dyed fibres before spinning.
Its surface is matte, so it photographs evenly under flat light.
