Have been enjoying reading this story about Eve Stuart-Kelso and her missing garden gnome: Murphy. He disappeared for 7 months, and was then returned complete with a photo album showing him having global adventures as far away as New Zealand.
How about doing this with your own gnome ?
With Smartboard 10 software you can cut out a gnome from an image (below is one I made earlier, with thanks to Flickr user Mr. Moor for the excellent gnome !), and then superimpose it on another image or location....
e.g. Here is a gnome with me and a Superlambanana in Liverpool !
