I'm new to sculpting and currently practising. I'm fine using a form to sculpt when there is a free edge to put the form under, what do people do when there isn't? I've got a bad nail biter coming for extensions in a few weeks. I've searched the Internet for tutorials but I can only find ones which use L&P. I think I'm going to have to extend the nail bed but how do I do this with gel without it sticking to the skin?
