Hi,

I have tried to stencil cookies but found that my bottom layer icing wont set hard enough and it ends up a mess.

Does anyone have a recipe or tips on how to get the icing to set hard?

AIs it royal icing?

yes that's what I have made, well what I think I have, lol

I flood my cookies with royal icing and let them sit flat for 12-24 hours.  They will be hard then and easy to stencil and wipe off if mistakes.  Not letting cookies have drying time will cause underneath to smear

as you pull icing over stencil.
