We make lots of charcuterie boards and have many molds.  But we're happy to share these great silicone molds with anyone who wants to create their own boards.
 
These molds come in standard sizes (13"x9", 18"x11.5", and 20"x12") that are perfect for many years of mold works.  Each is 1.5" deep and all silicone walls are 1/2" thick to ensure strength, while still being flexible enough to peel off easily without damage.
