My mother-in-law gave me a wonderful book for Christmas: rainy day book of things to make and do (you can find it at http://www.rylandpeters.com). I started to flip through it, and my kids wanted to do some arty seashell decorated frames from it. I find them lovely, simple to do even with toddlers, and as I happened to have a couple of cheap frames lying around we were able to do them spontaneously.
First we painted the wooden frames with acrylic paint, then glued buttons and seashells on them, chose pattern and colours for the background paper and a picture from an album to make a silhouette of. If we would not have started this spontaneously, I would have enlarged a picture and printed just the head for a model for the silhouette. Now I just drew on baking paper the pics my kids chose from an album (I advised them to pick something with a side profile) and then used those as a model to cut the coloured paper the kids chose.
