I fancied some really bright, summery nails, so decided to copy a diamond/ikat sort of pattern I'd seen. I used Greenberry, Grapefruit and the Yellow LE Barry M.
I created the pattern in pink and yellow with a dotting tool, then once it was dry (helped with fast-dry topcoat!) I outlined the two diamond shapes using a nail art pen. I did this using tiny line-type motions to make the edges look jagged. Another coat of topcoat and I was done!
