I don't know which words to search on in the forum to get advice so I apologize that this is surely a repeated question. Can you give me a keyword or two? We have a Dremel with a gentle setting, a file, small clippers (even a bit of acetone even though I know people say it's too harsh), basically, everything recommended and have watched a few YouTube videos. Getting them smooth has resulted in losing color and some I just can't get smooth no matter what. OMG please tell me there is a way. Also, just tell me the keywords and I'll search instead of opening a thread that has been opened a million times.
