Hi guys :)
I first saw this look a few years ago on Shirley from Meek -n- Mild and always wanted to try it but never got round to buying the reinforcements. However, I was in WHSmith and thought I'd finally give it a try. This is my first time doing it but I love how they came out and will definitely be trying it again with other colours.
If you click the link given above you can see Shirley's tutorial which is the one I used.
