I love the overall look and will make another one at some point, but do have a few minor issues with the one that I made, probably because I used a heavier weight polo shirt instead of t-shirt.

First I cut down the center and remove the collar and the buttons. As I used a 1 inch ribbon, I folded the edges over 1 1/4 inches and pinned it in place all the way around

The shoulders didn't lay right so I had to make a cut on each side at the back neckline at the shoulders before stitching all the way around.

As this is something I am just going to wear around the house, I didn't bother trying to cover it up, but the next time I make one I will probably use seam binding or bias tape to finish the edges to give it a more professional look.

I am also going to probably add a large bead to the bottom of each ribbon as it has a habit of sliding into the garment on one side then I have to take it out and re-thread the darn thing.
