Any helpful tips?

I'm using the cobblestone one on the sides of a castle cake.
Thanks!

Just make sure your buttercream is nice and crusted before attempting this, or you'll have a sticky mess! Also, my impression mat came with instructions to use a small roller, similar to the one for wallpaper seams, to roll it evenly across the impression mat. HTH!

agree with above post, make sure it is well crusted or it will be a disaster (I speak from experience)

you can use a paper towel, such as viva ,between the impression mat and the cake ,apply pressure to make sure you get a good impression, the paper towel will keep the mat from sticking to the BC .HTH

Yes, I can vouch for the sticky mess too.

But truthfully, I can't imagine using the Viva between it.
I understand using the roller.
Wouldn't you have to press even harder if using the paper towel?

If using a white buttercreme, couldn't you possibly lightly dust the mat
with either powdered sugar or corn starch? And I mean lightly.

Yes, the mat can be dusted with sugar or corn starch to prevent sticking.

Make sure you wipe the mat clean after each impression.

Thanks all for the great suggestions! Gives me a bit more confidence.

Y'all are the best!

the paper towel works you just need to use a bit more pressure than you would without and you could use the roller to apply the pressure evenly
