I've combined two challenges to make this simple, masculine birthday card.
First, Colour Q, where the challenge is to use black,grey, white and one spot of colour (I choose to believe in this case that 'happy' is one word, not 5 letters!). I chose my new favourite green - MFT Limelight.
And Retrosketches - a lovely simple sketch perfect for a graphic, masculine card. I hope that the letters (WPlus9 die) hanging over the grey/white border can count as the tail on the thought bubble. I finished it with a little Simon Says Stamp 'Birthday'.
