I was visiting Marion's blog here yesterday and came across a monthly challenge hosted by Green Paper - Mary Green . This is the first time I have participated. She posted a link to a PDF file containing 3 images - one of Lillian Russel, a room and a bouquet of roses each of which have to appear in the finished collage. The background is from an envelope I had previously made and I cut and pasted the images she provided as well as adding a few of my own.
The deadline for joining in is September 8th. Have a look! She also draws a name each month and the winner receives a collection of vintage papers.
