it all depends on how big your collection is going to be...I have found that I want furniture that all the dolls can use in any time period....and it doesnt really have to be AG.....a living room scene can be made from lots of different items...some you can do yourself...tables, jewel boxes make nice furniture pieces...candle lamps make nice table lamps..and as far as beds.....a bed of choice one you like....some of them will work with all the dolls and time periods just by changing the bed linens...kitchen pieces can be picked up rather inexpensively on Ebay...little stove sink and refrigerator...
