Step 4: Prepping the second shirt
We need to do this because the only usable part on your other shirt is everything below that sleeve line. Grab your scissors, and cut that second shirt all the way across, just under the sleeves. You can cut the bottom hem off that shirt too.
Next, cut up both sides of your shirt, along the seams. You should now have two rectangles of fabric. These are going to be the extensions we'll add to make our cardigan drape.
