Flip down kids table

I saw this plan a couple of months ago, and knew right away that this is what we need for our kids - their old table was always filled with papers, crayons and they never had enough space to store whatever they did.

I made the table longer so that it would be enough for both of them, and added foldable legs to support the table top.
Since I didn't find the right hinges for the legs, I used a piece of 1x1 with wood dowels which are attached to the inner side of the legs when unfolded.
