City Crafter challenge has a 2 colours only challenge.
In my Counterfeit kit was a green and red bracket paper from Fancy Pants. I mounted it on green card and found 2 photos featuring a cormorant displaying its wings.
I set myself the task of scrapping the whole page in red and green. (I hope I'm permitted white spots!)
I punched a border strip down the LHS and tied twine. I've matted my 2 photos differently to add variety in colour.
