Day 18 is Old Untried. I took this as, go into your stash and find something you've had forever and never put on your nails. Turns out I have a bunch of those (yikes!) so here they are, used and loved.
For this I used Sally Hensen Co-Bolt Blue as the base, and added Essie Blue Rhapsody and a gradient. I don't know why I had not used these before they are absolutely gorgeous. The dark chrome of Co-Bolt Blue contrasts so well to the light of Blue Rhapsody. Definitely eye popping.
