There has been a lot of discussion about using 'pot toppers' for terrain projects.
I first clued into them through a Yahoo terrain makers group.
Then, Tas mentioned them on his excellent VSF blog, Yours in a White Wine Sauce! [ http://pauljamesog.blogspot.com ]
So, I felt it only right that I should mention them here. I have yet to obtain any of them, although there is a Michael's craft store not a mile from my home. It is definitely in the project queue to try out, though, as it looks like it can be used to fantastic effect. To wit, check out this page: http://ardleybridge.fotopic.net/c1501517.html
If any of you have used pot toppers, please let us know your experience with them. How easy were they to work with, were you pleased with the results, what adhesive did you use - any comments would be great!
