For most people, winter usually means your favourite wool jumper is continually in and out of the wash. And if you’re anything like me, looking at care labels is not your top priority when you’re frantically throwing things into the washing machine on a Sunday morning, prepping for the week ahead.

I may have survived without destroying a piece of knitwear thus far, but I think it’s only a matter of time. So, to help you (but mostly me) take care of your wool outfits properly, I’ve enlisted the help of Penny Ashby, founder of Australian Merino wool apparel label, Lady Kate, and a wool-care connoisseur.

Ahead are her tips for caring for your wool jumpers to ensure peak fluffiness and warmth for years to come.

Don’t Use Hangers

“It’s always best to store knitwear folded, to maintain its shape,” Ashby says. In other words, try not to put your wool jumpers on hangers as they’ll stretch and might permanently deform.

Always Read the Care Label

Because different wools require different care, Ashby strongly suggests always following the care label on your garments as best practice. So, trust in your knitwear designer, they “know their fibre inside and out”, she says.

Never Wash Wool Jumpers in Hot Water

Unless, your care label says otherwise, washing your wool jumpers in hot water is a no-go. Ashby’s secret to washing her own knitwear? Using cold water, gentle or wool cycle with an approved wool detergent.

Dry Your Knitwear Flat

I’m sure we’d all love our knits looking as fresh and bright as the day we bought them so follow Ashby’s advice.

“Dry wool garments flat, out of direct sunlight and your knit will last you year after year,” she says. If left in direct sunlight, wool can scorch — leaving your knits frayed and discoloured.

Be Smart with Storage

When winter is done and dusted, you can prevent moths from eating away at your wool jumpers and knitwear by storing them in thick cotton bags instead of plastic. Ashby mentions that doing so allows your garments to air out and stay dry even through humid weather. And she suggests keeping the bags or storage area scented with strong oils like lavender and cedar.
