I tried searching through the Forums about similar threads but couldn't find any, so here goes. I think there needs to be more types of items in the game that don't really have a purpose. They have gems and shiny items and music blocks and such that have no real purpose, but I think they should add more items that are just weird little knick knack items so I can put them all over my house.
Some examples: african style masks, birdcages, watches or clocks, weird paintings, lamps that you can turn off and on, decorative flowers, wine and glasses, baskets, picnic baskets, vases, etc. Or maybe you can use planks to make furniture or picture frames that you can put your own uploaded pictures in.
Just little items you can decorate your house with. A lot of the items are too common so making them more rare would add more fun to getting these items and make them worthwhile to auction.
