One year he bought me a This American Life t-shirt (to go along with the one he already had) which never quite worked out. It was an awkward fit at first, then proceeded to shrink in the wash. But I couldn't bear to let it go to waste.
Although I detest sewing with knits, I feel moderately comfortable modifying and resizing t-shirts. This is what I started out with:And here is the final product:
idea was loosely based on one I found while perusing Dana's MADE blog. I simply cut off the top right below the sleeves, gathered it onto a piece of calico, made it into a casing, and threaded elastic through it. Strips of the leftover knit (no hemming needed) were then sewn on to make straps.
