Day 1 - I used a wooden skewer and a colour shaper to apply the masking fluid.  

Day 2 - Two layers of masking fluid and two colours

                                      Day 3 - Masking fluid applied with an old toothbrush.

Day 4 - Masking fluid applied with a chop stick, two layers and two colours.

I have always wanted to explore masking fluid so this was a great opportunity to do it. However I realised I was actually avoiding the project that I really needed to start...

Thank you to your class, I have finally started a project that I have been putting off for a long time!
