Hi everyone. Just thought I'd ask if anyone can advise me on a Thumb Sucker! A lady has approached me asking if I can apply nail extensions on her nails for a wedding. All seemed fine when she flashed me her nails and then she showed me her thumb which looked abit soggy and nibbled ! Then she said she sucks her thumb and has tried the stick on nails from the chemist and they won't stick to that thumb and would mine. Has anyone tried this before or experienced this before?
