I used the sleeves from my Ninja Turtle's t-shirt as a guide for cutting down the original sleeves too. Sprint had made their mark on one of the sleeves as well, so I had to do something about that. I lined up my two sleeves folded out flat and cut them both together to remove the Sprint logo. I then used these cut out pieces as a pattern to cut out two matching segments from the blue t-shirt and sewed them back together. Make sure to allow for some seam allowance when you do stuff like this so that it returns to its original shape.
I then placed them back into the arm holes and here you have it...a way cooler more flattering t-shirt. The web cam flips the image so..."Royals" looks backwards.
