For children’s art classes, we would strongly recommend considering joining other art-K clubs that are close to Wimbledon, such as Wandsworth and Putney. If you follow this link and search your address it will show you which is closest! You will be able to join the club far quicker than Wimbledon as it is currently overbooked/waiting lists are long: https://www.art-k.co.uk/club-locator/
