I believe that is a stencil from Designer Stencils. I use them all the time. If you frost your cake withÂ buttercream or fondant and chill it for about 15 minutes in the freezer and use buttercream to stencil it chills immediately and does not smear. Love them.
Thank you so much!Â I did find the stencil there.Â I've never used a stencil before but it looks pretty easy!Â Thanks again!
