I decided to make the Clara table and the $4 stackable chairs for my daughters for Christmas. They were not for them though but rather for their American Girl dolls. I had to modify the plans to work for standard 18" dolls.
The Table:
It is a little taller than it should be but it allows the doll to fit under the table/apron while sitting in an appropriately sized chair (5" seat).
I also changed the length from 18" to 15 1/2" so the cuts could be made from a 4ft board.
3 - 1 x 6 @ 15 1/2" (Top) (1 @ 4ft)
4 - 2 x 2 @ 10" (Legs) (1 @ 4ft)
2 - 1 x 3 @ 10 1/2" (End Apron) (1 @ 4ft)
2 - 1 x 3 @ 9" (Side Aprons)
The apron is 1 1/2 inches. a 1x2 would probably work for the aprons too. You could then shorten the table legs by about an inch.
The Chairs:
The over all dimensions are now 12" H (back), 5 1/2" H (seat) X 6" W X 6 1/2" D
Cut List:
2 - 1×2 @ 4 1/4" (Side Aprons)
2 - 1×2 @ 5" (Side Supports)
3 - 1×2 @ 4 1/2" (Front Legs and Front Apron)
7 - 1×2 @ 6" (4 Seat Slats, 2 Back Slats and Back Apron)
2 - 1×2 @ 12" (Back Legs)
