Would you attempt to put these scales on buttercream? Should I cut them out and let them dry completely. Customer wants a 10" 6" with scales on the bottom but only wants buttercream I'm afraid it will pull the icing off.http://www.cakecentral.com/g/i/3045628/little-mermaid-cake-fondant-scales-disco-dust-candy-shells-modeling-chocolate-rock-dragees/
See my link. I put the petals on crusting buttercream. It held up but when the cake was cut they fell off. I would probably let the cutouts dry a bit so they will be more manageable and will not lose their shape as you place them on the cake.
