Mr. & Mrs Stencil. I used 2 stencils for this wedding biscuit. My stencils are a standard 130mm x 130mm, the extra room on the edges allows for them to be secured by magnets to avoid any sliding or shifting when airbrushing or using royal icing. The plastic is thick enough to not bend and be used multiple times. Magnets and metal boards are available for purchase too. Stencils are made from a food safe plastic.
