Cut off a 21-in.-long board for the shelves, rip it in the middle to make two shelves, and cut 45-degree bevels on the two long front edges with a router or table saw. Bevel the ends of the other board, cut dadoes, which are grooves cut into the wood with a router or a table saw with a dado blade, cross- wise (cut a dado on scrap and test-fit the shelves first!) and cut it into four narrower boards, two at 1-3/8 in. wide and two at 4 in.
I recently came across this beautiful wooden swing set, which was made in the shape of a boat. Cool, isn’t it? The very first look was enough for me to start loving it. Although I haven’t yet tried building one myself, I am definitely going to. Later I realized that you can also build a baby cradle with the same idea. After all, what can be more calming than the tender rocking of a boat? This swing set will surely help your child get more gentle sleep.
