I wasn't sure if this is the right area for this topic, so if not, Julia, please move to appropriate section.
So, I am a beginner and at times get sloppy with royal icing. So I have finally finished a cookie that I am really pleased with but unfortunately I did get some icing on the sides of my cookie from my messy hands. Is there an easy way to take that off? I used a sharp knife to scrape it off but just wondered if there are other tips and tricks (besides not being a messy decorator which I am trying to improve on). Actually, I have decorated cakes and cookies for years with buttercream and fondant, but have always been interested in royal icing so I have jumped in with both feet.
Thanks in advance.
