Colour Switch Swatch

I'll admit it. I'm a nail polish addict. I can't go into town these days without a quick pop into Boots or Superdrug to see if there are any new colours that take my fancy.  Saturday was such a day.  I've seen lots of this type of colour switch nail polish - where you pop on a top coat and the polish changes colour, but haven't got around to trying one yet.  I got a Boots 17 one, in the imaginatively named 'blue', which is hardly blue at all when you've got it on your nails but in fact more purpley. [Edit - strangely it's now looking a lot more like blue] I figured it'd be fun to do some nail art with this one, so out came the scotch tape again.

The polish itself wasn't particularly easy to paint on.  Because of the metallic nature of it it was a little streaky and the brush is horrible.  This was two coats of the polish, then I let it dry completely for an hour or so (it didn't take long to be dry to the touch) before I put on the scotch tape and used Butter London's PD Quick on the top to change the colour.  I left the scotch tape in place for probably 2 hours before taking it off to ensure it was completely dry - and I wanted really crisp lines.  I'm pretty pleased with how it turned out, but not sure how long it's going to stay chip free (it's a bit annoying not being able to put a top coat on to protect/smooth the lines!)

Have you tried any colour switch polishes? What designs did you do?
