Thanks for all the nice comments.
It took 3 long hours in the end.
I soaked them off in a deep bowl, with lots of acetone, as my Easy Soak bowl could not be used, due to the length. Then very very carefully preping them, before applying acrylic overlays. I used a form on the little finger as this one was already broken half way. She wants me to make this one longer though at the next appointment.
Finally finishing them off and making them as smooth as possible. (I'm a stickler for ensuring all the nails I do are completely smooth and correctly shaped).
Then applying the Gelish colour Caution.
She said I have free reign as far as nail art goes. Next time it will be much easier just doing the infills. I just need to get my thinking cap on for some funky nail art now!
Long job, but obviously I charged her a fair bit extra due to time and products used. Feeling much better about them now. Feel I can deal with any length of nail after this.
Rather pleased with myself. Most of all the client is very happy with them and has booked in again for her infills etc.
