upholstered chair

This is an upholstered chair that I made based in patterns from a Japanese dollshouse book. I am not very happy with the final result, but I have learned a lot! One thing I learned is that is very difficult, almost impossible (at least for me) to get ride of the ruffles in the back chair, because the seat is round, I tried to strech the fabric as much as possible, but the result is always the same, ruffles!!!!!!!!!!!! so, now i am trying to make another kind of upholstered chair, complete different design....
