My daughter asked for another shelf in her room. Here’s how I made it.
[Below] I had an old pine board which had previously been employed in a bookshelf at our church. I planed it both sides to remove the dark stain and correct a slight cupping. (I wish I had photographed that as a tip. Basically you support the concavity with a strip of wood, then plane it off.) I ripped the board down on the table saw and cut out the length of shelf I needed. You can see the pieces that resulted.
[Below] Taking the one large piece of scrap, I divided it with a line diagonally and freehanded a shape for the shelf brackets using just one half.
[Below] After cutting it out on the bandsaw I used the newly cut piece as a template and drew a copy on the remaining half.
