The designs I create, look detailed and delicate but require little or no assembly. They consist of a silhouette shape with the details cut from that shape. If you would like just the silhouette shape with out detail, ungroup the design and delete the detail. Here's a link to Silhouette's blog about ungrouping if you're not sure how to do that: http://silhouettemachine.blogspot.com/2009/12/monday-cafe-its-group-thing.html .
(For those looking for the Roman Colosseum, that one is first on my list and is actually partly done on my computer right now!)
Here's an example of some that are already for sale in the store:
Eiffel Tower in Paris, France
Golden Gate Bridge in San Francisco, California, USA
Taj Mahal in Agra, India
Niagara Falls on the border of New York, USA and Ontario, Canada
