Laser cutting felt fairisle brooches

Posted Posted in Designers, felt

Donna Smith Design is a knitwear designer on Shetland. Donna teaches knitting and design workshops around the world. She got in touch because she wanted to create felt brooches of her own design and wondered if they could be laser cut.

Fairisle jumper artwork

Donna sent me vector artwork with a design for a fairisle jumper. It had a pattern of round holes that were to be cut out around the yoke. There were also slit cuts to be made at the cuffs and the waist of the jumper. Both sets of details were well spaced and robust

I made a prototype from 3mm plywood as I don’t have felt in stock. It was possible to see through the slit detail, something that I’d never cut before. Donna was delighted with the effect.

Felt properties

Donna sent me four colours of felt to cut the jumpers from. I hadn’t cut felt before. It’s always interesting trying out new materials! Sometimes it all goes to plan and sometimes the unexpected happens.  

With a soft, flexible material like felt, you have to think about products stretching and distorting as well as general robustness. But this felt was much thicker, stiffer and chunkier than other felts I have come across and it wasn’t easy to stretch. It was better suited to making brooches than I’d expected.

Prototypes

I test cut some brooches to check the results. First, I tried my short focal length lens as felt is usually only several millimetres thin, but the felt was getting scorched.

Next, I tried a longer focal length lens that would be focused further away from the surface of the felt. This time, I didn’t get any scorching and I cut the rest of the brooches. The felt cut really well and the cut out detail worked really well.

Contrasting detail

When Donna published photos of the finished brooches, I noticed that she’d added contrasting detail with wool embroidered through the small laser cut holes. It finishes them off perfectly!
