For twenty two years I have knitted jumpers by hand for women who feel invisible in the activewear aisle. This is not a fast fashion story. It is what happens when a woman spends two decades chasing one perfect stitch.

The Petra is the jumper I make for the women who gave up on soft wool actually keeping them warm. Every fibre is chosen, every seam is finished by hand, and every colour is picked to sit quietly beside the clothes you already own.

Most high street jumpers are cut from acrylic blends that trap heat for an hour and then turn cold and clammy. The Petra is knitted from a grade A cashmere blend that breathes with your body, so you stay warm from the moment you put it on to the moment you take it off.

Tight necklines dig in and loose necklines slip off the shoulder all day. The Petra sits exactly where it should, flattering the neck and collarbone without a single adjustment needed.

Knitwear is meant to be forgiving, not shapeless. The Petra is cut close enough to flatter the waist and loose enough to move with you, so you never feel wrapped in a blanket.

This is the part women write to me about the most. Full length sleeves that actually cover the arm properly, cut slim enough that they do not bunch under a coat or blazer.

Oatmeal, sage and charcoal. Three colours chosen because they sit quietly with the trousers and skirts already hanging in your wardrobe. Nothing about the Petra asks you to start over.

You have not done anything wrong. You have just never been shown what a properly made jumper is meant to feel like. Most women are one wear away from noticing the difference.

Six months ago my business partner and I split, and with him went half of our stockists. I was left holding a warehouse full of jumpers I had already paid to have made, with nowhere obvious to sell them.

Rather than send them to a liquidator, I am selling them directly to the women who will actually wear them, at a fraction of what they were made to sell for. Once this batch is gone, the Petra goes back to full price.

The Petra will not be part of the next collection. Once this run sells out, it does not come back at this price. If you have been putting off buying a proper jumper, this is the one to stop on.
