I have been doing a lot of work with my Mini treasures wiki lately and therefore I am promoting it to you . See e.g. the projects page with list of different theme projects:
Some ideas from that page for you to think - what would you like to do next:
apples, bags, cats, dogs, easter, fireplaces, geeks, hello kitty, italian, japanese, kebabs, laundry, mice, nursery, office, pandas, queen mary, rabbits, shabby chic, trash minis, uglydolls, victorian, witches, yellow, zen?
There are nearly 700 pages already so I bet you will find something that interests you there :).
Have a nice time in the wiki!
