This is a tricky one because it is all down to how ‘floriferous’ you would like your cake or dish. Generally speaking we roughly recommend one box per tier – the three pack is enough for a three tier cake (10,8,6 inch) with a slightly larger display on the top and two boxes to decorate the shoulders of the tiers. If you want additional flowers for the base of the cake – i.e. if it is sitting on a board or tray then you will need a few more. The number of flowers per box is listed on the product page to help.
