http://morethanwordschallenge.blogspot.com.au/ has a numbers and family challenge.
I've used a white background and misted over with a gold outline of cogs.
Both my daughter and I are thinkers/dreamers so the cogs turning signify us.
I matted in purple to match my top, but also because it is her favourite colour.
The numbers are black leather, I thought they made a great texture.
The layout is pulled together with gold and white washi tape.
