My first thought was "this would be a cute garden potting shed".
And it's cute but a bit cluttered. So I built a little swing!
I'm going to add flowering vines to the ropes. Actually, I may have to re-do the seat- it's hard to keep the doll on it. But it's adorable! And putting it together was cheap. No more than $20- with the sale and coupon, the terrarium was $18, and the supplies I had on hand would have been about $2!
Also, while I was looking for parts for the swing, I found some of my old dollhouse furniture! It's perfect for mini Rebecca. Big Rebecca's old collection had a similar sofa (not blue, though). I'll have to get a little menorah for the table. This is definitely going to be Rebecca's set!
