Built the sewing table for my wife Penney. It has a work surface that is 36" x 60" and is 32" high.
Used 3/4" Baltic Birch and used premium pine to add edge banding. Used 1/4" plywood for a back to the sewing table to add strength and I think helps the look of the table. My Kreg Jig was used everywhere possible when assembling the case. Used full length piano hinges with #6 x 5/8" screws to attach the leaves to the table. Made the doors using premium pine with a plywood panel. For the legs, I used folding, locking leg brackets from Lee Valley to attach the 1-1/2" square poplar legs. The casters are 3" double-locking from Woodcraft.
Went a little over budget, but it turned out very nice and she loves it.
Thank you for the easy to follow plans.
