Treefrog Art designs and delivers imaginative, engaging art workshops. It was founded by Vicki Ostersen in 2018 to promote creativity in all areas of the community. Workshops provide opportunities to explore lots of different materials and techniques, whilst encouraging individual expression.

Drawing, painting, collaging, cutting…  Working with watercolour, buttons, dye, glue… Treefrog Art encourages dexterous fingers and hand-eye coordination. Workshops inspire confidence in all generations, and celebrate individual and collaborative achievements.

Treefrog Art Projects showcase the collective creative energy of schools and community groups. From 24 to 360 participants, at the heart of any Project is the belief that there is real value in the contribution of every individual.

Treefrog Art courses give opportunities to develop new skills over a period of days or weeks.

Explore, get a little messy, use your imagination, do things differently, challenge yourself, and have fun!

Testimonials from Art Club

‘Children from Froxfield Primary School had a truly great experience building a mosaic with Vicki and Louise. Tremendous care was taken in reflecting the children’s thoughts, ideas and wishes into the final artwork design. Building the mosaic had a profoundly positive affect on every single child, without exception. We are hugely delighted with the final result which perfectly represents our school.’ Mrs V Farrow, Head Teacher, Froxfield CofE Primary School.

‘What a beautiful, vibrant, colourful display. Really welcoming and spring-like.’ Tearoom customer – Art at Winton House

‘The artwork is fabulous! The children have all worked so hard and are super proud of what they have produced. Lovely café too- will definitely come again.’ Year 1 parent – Art at Winton House

‘Thank you Vicki for such beautiful work and for all the time, energy and commitment you put into working with the 350 fantastic children from Petersfield Infant School. Looking forward to our next project together!’ Rachel Harford Centre Manager –  Art at Winton House

‘Had to let you know that each time I have visited the garden this week I have bumped into little people bringing followers to look at their stones. They have brought so much pleasure to so many people. You really did do a fantastic job. 😊 Thank you.’ Rosemary Clark – Art in the Physic Garden

Both of my children spent time at Petersfield Infant school creating projects with Vicki, from the visually stunning stones project that was displayed in the Physic garden (my son sleeps with his stone each night to this day!), to the excellent exhibition ‘A Brilliant Day’. The exhibit showcased our business and brought new customers into the fold of the Townhouse family – thank you Vicki !  Dom Humphries Owner
