And how better to do that than by using a bicycle wheel and a tea kettle. How very English.
Her starting point for the project was the discovery that some charity shops devoted hours to unravelling home-made sweaters:
They can make more money out of selling the wool than they can from the sweaters.
It's funny but serious. Hedges won a prize for the un-knitting machine. The machine is made out of an old bicycle frame, a kettle, a spindle, and a stool.
The un-knitter (?) sits on a chair and pedals the bicycle wheel while the wool passes through steam coming out of a kettle. The wool is softened as it passes over the steam.
The wool is then collected on a spindle.
As she explains:
My grandmother spent the whole time knitting sweaters but my mum threw them all away once we’d grown out of them because she didn’t think anyone would want them. With my machine you’d be able to take them apart and knit something new.
