Knitted Knockers



About Knitted Knockers South Africa

Knitted Knockers South Africa was founded in 2014 by Ruth Archer and Dana Biddle. We are a registered NPC (2020/107733/08) and are proud to be partnered with CANSA South Africa.

A Knitted Knocker is a 100% cotton knitted/crochet prosthesis for breast cancer survivors who have had a mastectomy. They are offered FREE to women who have undergone mastectomy/lumpectomy surgery, as an alternative product to the silicon prosthesis. We also offer Knitted Knockers to women who are awaiting implants, have had their implants removed or are undergoing radiation treatment.

Knitted Knockers are soft and comfortable to wear in a regular bra – no special prosthetic bra is required.

Knitted Knockers SA researched all the different groups around the world and their patterns and decided that the Australian knitting pattern would work best in South Africa since our conditions are so similar.

Julie Weaver, who designed the knitted prosthesis to suit Australian women, especially those who are well endowed, kindly agreed to let Knitted Knockers SA use the pattern she designed which has a size range from A to G cup, we have added the larger sizes. Her pattern also has a built in “buttonhole” so that the filling can be removed for washing or changing.

When testing we also found that most crochet also causes irritation and discomfort because the crochet fabric is not smooth enough due to the ridges that crochet forms. With this in mind, Stephanie Davies designed a crochet knocker pattern that has no ridges, making it smooth and comfortable to wear. We now have crochet kits available too.

Knitted Knockers should only be knit/crocheted from the softest, pure, natural cotton that has been dyed without the use of harsh chemicals because other fibres can irritate the sensitive skin and scars. 100% merino wool filling breathes and so is comfortable to wear in any weather. The approved Pure Cotton yarn and Pure Merino filling is provided, with a pattern, in the official Knitted Knockers South Africa kits.

Knitted Knockers South Africa cannot use any prosthesis that have been made from an online/downloaded pattern or that aren’t knitted/crochet using the approved materials (and patterns) provided in the official kits. Please help keep Knitted Knockers high standard of quality for breast cancer survivors.


Knitted Knockers are only ever gifted, FREE, as support for breast cancer survivors.
