I have been doing this type of toe nail art for aaaages! I tend to use a variety of sizes though, that way, there are less gaps inbetween stones, and you get a much blinger effect. I tend to prep the nail, dehydrate and cleanse with Scrubfresh and then do each nail in sections, quarter sections usually.
I apply a coating of The Edge resin in one quarter and quickly add rhinestones using a dampened orange stick. I also use tiny flat 'chunky glitter' inbetween the stones, Millenium Nail's silver 'randbow' effect ones are the best. Just keep going until the entire nail is coated, and spray with resin dry spray. I never apply a top coat as it dulls the stones.
I always apply my stones like this and they last upto 3 weeks. Removal is easy, soak them off in acetone, takes 5-10mins
I get my stones from dreamtimecreations.com
