I mill the shelf parts to 1/4" in thickness and everything else to 3/4" in thickness.

I cut the side pieces to their rough sizes at the miter saw.

At the table saw, I cut the sides, top and bottom pieces to 1" in width.

I use a stop block at the cross cut sled to batch out the sides, top, bottom and shelf pieces to size.

Before gluing up, I sand the inside of the frame pieces with my orbital sander.

I used 3/8" dowels for the joinery methods.

The top and bottom pieces are inset 1/8" from the edge of the side pieces.

The 3/8" drill bit has a stop collet on it and is set to drill 3/4" deep in the side pieces and 1" deep in the top/bottom pieces.

Since the side pieces only have a 3/4" hole, I removed 1/4" from the dowels.

With the piece put together (before glueing up), I mark the lines for the back panel grooves. The top and bottom pieces have the groove going all the way through and the side pieces have a stopped groove. I got into a little more detail in the video.

I used a 1/4" router bit set to 1/4" deep and flush with the fence.

The side pieces get a stopped groove.

Everything lines up.

Now that the grooves are cut, I glue the frame up.

The shelf has a curve in the front. I marked it using a throat insert from my spindle sander.

Cutting away the waste at the band saw.

I used my spindle sander to smooth the edges.

Normally a disc sander would be used for outside curves but this came out good enough.

With the glue dried, I sanded the frame with 80 - 120 - 180 grit sand paper

I round over the edges with a 1/8" radius round over bit at the router table.

Glueing on the shelf.

Clamping the shelf into place.

The shelf supports are made using a 1/2" radius cove bit.

I used my cross cut sled to cut the 3/4x3/4 shelf supports.

Next step is to glue the shelf supports in place. They are inset 1/4" from the edge of the shelf.

2 supports are all that are needed.

After the shelf glue dries, I ease the edges with 120 grit sand paper.

Its finally time to apply the finish. I used a semi-gloss varnish from Arm-r-seal.

After the first coat dries, I sand with 220 grit sandpaper and apply the second coat.

To hold the back in, I used a couple of 1" picture frame buttons.

Putting the nails in the frame wall mount.

To keep the bottom from hitting the wall, I put 2 felt dots on the bottom.
