Rebecca and then again a similar version by Deniz - check out their posts! I used GOSH Metallic Purple and MUA shade 13 for the larger dots :-)
And Rebecca was right, it's hard to come up with names for dotted manis so I went with "Going Dotty"...Lol!!
(Apologies for the picture sizes, my camera had different settings for each of the pics and I only noticed when I had taken all the pics!)
