Something about zig zag patterns just brings the word snazzy to mind, one of the best silly words! Another simple summer design, all you really need is a nail art pen. For this design I used all Barry M colours. I find their nail art pens are reasonably priced and easy to use, but you definitely need a top coat, as the desing will start to rub off otherwise. Also need to make sure the nail polish is super dry before you start the design or it can start to drag the colours. It's best to make sure there is quite a lot at the nib of the pen so that it glides easily accross your nail.
Colours used: Mint Green - Barry M, Berry - Barry M, Nail Art Pen in Black - Barry M
