I had yet to use my Shellac Blackpool on myself, so decided to try it out as my nails are quite short at the moment and look good with a dark colour on them. But black was too plain, so I put a small 'lightening strike' nail art detail as an accent nail on my ring fingers. I used some simple cheap silver diamantés from eBay - I think they were about 1-1.5mm - and placed them in the top coat before curing.
Simple, yet effective! What do you think?
