who we've worked with...
Since 1995 Helen Johannessen has worked with a long list of lovely clients. This mainly involves model making, mould making, slipcasting and prototyping.

(works still being added - be sure to keep popping back)
Sena Gu - Studio Gu
Sena is a recent talent from The Royal College of Art. Yoyo has worked on a couple of pieces with her. What we love about her work is the initial simplicity, yet upon a closer look, each ceramic creation has the most carefully considered detail.

We love her obsession with cauliflowers and lemons too…take a peek at more of Sena’s work at Studio Gu
Takae Mizutani
Takae designed these cute ceramics, usually with a food related theme. We modelled and moulded. Just imagine a bit of Swiss Roll on that snail plate!
Jacqui Chanarin
We worked with ceramic artist Jacqui on a number of her sculptural cast pieces. Modern ‘ornaments’ perhaps is a way to describe them.
Jacqui sells pieces in The New Museum in New York where you can read more about her.
Adele Brydges for Coco de Mer
We worked with Adele who was commissioned to design accessories for the Erotic Boutique based in London and LA - entitled “Adele Brydges Loves Coco de Mer’
See more work from Adele or for more in the designer sex toy collection at Coco
Peter Ibreugger
Peter is an fine artsist who has realised some of his ideas and illustrations into ceramics with our help over the years
See the varied (and sometimes risque) ceramics and other work from Peter
Liz Emtage and Kim Robertson
A collaborative project between Liz, a ceramicist and Kim, a textile artist. This is a new venture for them into casting; producing these fresh tealight holders/vases.
Liz hand makes porcelain lighting and Kim prints on fabrics and produces stationery products
David Weatherhead
David came to studio Yoyo as a student of The Royal College of Art. I have never made a bigger mould before (or since!) Press moulded, and the size of a decent sized cardboard box…
Am loving his Round and Round calendar on his website
Molly & Berts
Jo Heckett and her husband set up Molly & Berts in 2007 to show a little bit of London life with modern graphics and cockney ryhming.
They produce printed T-Shirts and ceramics…which is, of course, where we came!

Erica Gohdes
Erica was a student at Goldsmiths when she approached us with her ‘different perspective’ project. Each cup is an isometric drawing translated literally in 3D. Some pieces were painstakingly hand built in slices of clay to achieve the effects. The one on the far left was the most feasible to work as a cute ‘drawing’ realised
Erica seems to have taken her creative skills into acting, singing and modelling now so if you need a lovely leading lady look no further!
Flavia Del Pra
Flavia and I used to share a studio in North London…until she (sadly) moved back to Brazil with her flamboyant approach to ceramics and pattern. I worked on her with the lamp bases and am happy to say that I own the lamp on the left here…
For a feast for the eyes and more daring colour schemes!
Claire Coles
Textile and wallpaper stitcher extraordinaire Claire steps into the world of porcelain. She and I developed her floral vases shown here…

… and we have been working on collaborative projects. You can now buy Claire Coles in the Yoyo Shop
Martina Von Meyenburg
Swiss born Martina is a conceptual artist who needed to realise her ideas in ceramic form.
We aided her with this project…

Alon Meron & Rory Hooper
Alon and Rory approached me as RCA graduates with a computer rendered drawing to translate a into porcelain piece (entitled Thank God It’s Friday) This sculpture was slip cast and then hand assembled upside down directly onto a kiln shelf. The 60cm long piece was then fired and turned right way up with fingers firmly crossed…
One of the most challenging concepts to work out and produce to date.
Alon is a product designer and Rory a jeweller
Alon Meron
We continued work with Alon on his Buba - a ceramic character who is a dark take on the tooth fairy
