The reason I decided to do them now was thatI wanted a fairly neutral design for when starting a new job. I've been told that many companies wouldn't be too happy with their employees using their digits as mini-canvases but luckily that is not often the case in engineering.
The base colour I'm using is Mint Choc Chip by 17, a lovely colour but not very good quality - it chips easily. For the dots I used our beloved pin (from sewing kit) and then I drew around them with a permanent marker. As I applied the topcoat the marker smudged a lot more than I expected, which worried me, but at the end of the day it actually helped the design.
Pastel colours are also a great way of reminding yourself of the upcoming (sometimes visible) spring!
