Heleen Klopper of Woolfiller

Woolfiller's very own Heleen

Meet Heleen Klopper, product designer and founder of the much-loved Woolfiller. With sustainability, repair and tradition being key elements in her practice, Heleen was keen to bring back the ways of the past, when holes in woollen garments were mended by hand, rather than thrown away. Named as one of the 50 best inventions of 2010 by Time Magazine, Woolfiller makes clothing repair easy and accessible for everyone.

Tips for garment care


You can shrink it

"I inherited a number of thin cashmere sweaters from my father, that were size XXL. I asked my best friend Erik, who regularly accidentally shrinks his sweaters, to wash these too hot as well. 😛 

His method? Wash the sweaters (in a full drum, with soap) on a short regular program at 40°C. 

Et voilà! A lovely sweater in size S/M with a nice firm quality."

Grease stains

"How do you get a grease stain out of your clothes? With talcum powder. Talcum powder comes from the mineral talc. It's a magnesium silicate and absorbs moisture insanely well! 

Generously coat the stain with talcum powder. The sooner you do it the better! Leave the talcum powder for at least an hour before tapping or vacuuming it away. If the stain has not gone, repeat it again."


"Sometimes I transform old woollen sweaters into vest tops by cutting the sleeves just above, or just below the shoulder seam. The result is a funky and chic new item of clothing from an old one!"

Dyeing for your clothes

"Something I like to do that lets me enjoy my favourite items for longer, is take them to Hul le Kes Dyeing Service. They dye fabrics with natural dyes, which results in unique makeovers for your clothes. Say goodbye to faded colours, yellow stains under the armpits, dirty collars, spilled red wine... you name it. Keep a look out for a similar clothes or fabric dyeing service in your area."

made to mend

made to mend is a reinforced tweed fabric that Heleen developed, that allows easy and infinite mending, inspired by traditional darning. They create clothes and accessories made from this new material. Designed for the future. It's a resistance to the fashion machine that manufactures clothes as disposables. 💪

Made to mend quote: a future proof material

Forever yours

The fabric comes in three structures: 

• 1:1 is fine and is the strongest

• 3:3 is coarse and is the easiest to repair 

• 2:2 is medium and has a little bit of both

Sampler bag from made to mend

Heleen's favourite piece from made to mend is the Sampler Bag. An everyday carrier that is subject to wear and tear, but can be mended time and time again. Complete with a handmade twill darning mark to celebrate and promote repairing.
