the first time i ever saw water marbled nails was on jackie storie, at a wedding. she did an amazing job, so i youtubed it and tried it myself. ive never really been able to execute it that well!! (or photograph it that well.. sorry about that). i always have problems with it.. not to mention that its time and labour intensive! it probably takes about an hour and a half to plan your colours, prep your nails and equipment, tape the skin around your nails, do the marbling, and clean up. also, i know there are some detractors out there in the nail blogging world that arent really fans of nail marbling.. but if its done well it looks really neat and no one can ever figure out how you did it!!!
