Digital Collage

I have long been a fan of retro and vintage digital collage and recently started to create my own digital collages. I had a feeling that although they have an 'easy' feel about them they would prove to be more difficult to do in practice and this has been the case. However I do feel I am beginning to get the hang of them. There are some good on-line tutorials about creating them and I have a board devoted to my own digital collages on Pinterest.
