Drying
Never hang a wool sweater to dry.
When soaked, the weight of the water stretches the fibres irreversibly.
Once the excess water is removed, lay your knit flat on a terry towel. Roll it gently and press to let the towel absorb as much moisture as possible. Then unroll and dry flat on a drying rack or another clean towel. Always flat. Always without tension.
Removing pilling
Proper washing and drying will help, but pilling is common with wool.
It requires the right tools and a bit of care.
Pilling is caused by friction — from another garment, a bag, or the knit itself (under the arms, along the sleeves…). The most exposed areas are usually the most affected.
To prevent it, regularly use a fabric brush or lint roller to smooth the fibres.
If needed, use a fabric shaver (with safety grid) on the gentlest setting, or a pilling comb.
A classic razor may also work, but use it with extreme caution.
Note: blended fibres tend to pill more than pure wool or cashmere.
Storage
Always store knits folded flat in a drawer or on a shelf.
Hanging them stretches the shoulders and distorts the shape. Over time, the piece can grow by several centimetres.
Moths are another invisible enemy.
Place a moth trap in your wardrobe, and use cedar blocks or cedarwood essential oil to repel them naturally.
In spring, store your knitwear in vacuum-sealed bags — it saves space and reduces risk.
In all cases, always wash your knits before storing them. Moths are drawn to sweat and residues.
