Just Sew: Sweatshirt Blazer

Two very different looks created from the same sweatshirt:

After removing cuffs, neck, and bottom band, it takes about thirty minutes to add lapels and finish the edges to make a ruffly, feminine version of the grey sweatshirt.

Taking it a step further, you can dye the sweatshirt and add jersey "piping" to give it a more formal look that is still as comfy as an old sweatshirt.

Step one is blogged about here and step two can be found here.
