I'd restructure the site.

It sounds like the sizes, shapes and colours are options to a single line of products. No need to create independent products for each combination because you'll either end up with duplicate content (even if the words aren't exact, the intent is) or looking like an idiot for rewriting the same copy 200 different ways! :)
