Anyway, week 2 is a simple colour theme- blue! I was excited by this week as blue is my favourite colour, and thanks to pinterest (I'm addicted again) I had the perfect inspiration- this awesome design and tutorial by Nailed It, and I'm very glad I did, the liney/gradient effect is pretty cool and would work so well in other colours and textures- another great technique to know!
I used No7 Minty Fresh as a base, then I used a medium length brush to paint the longer stripes in No7 Stand Back over the top 1/3 to 2/3 of the nail and then Models own Aqua Violet right on the tips :)
Do have tutorials and designs that you 'need' to do? I have a whole list!
