‘Creativity is contagious, pass it on’, Albert Einstein

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!

‘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’.  I retain the cooperative piece on permanent display in my business! The exhibit showcased our business and brought new customers into the fold of the Townhouse family – thank you Vicki !  Dom Humphries Owner
