Welcome to the Cake Decorators Q&A

What size MDF board are you using and what size dowel?

Thank You

Hi Carlene

At a guess I would say that is 10 mm board and either 7 or 9 mm dowels. For a more definitive answer it may be wiser to contact the site here: https://designer-cakes.zendesk.com/hc/en-us/requests/new

Hope this helps.
