Have you ever just gotten a shirt and only worn it once before it got a hole in it? Bummer:( This happened to me recently and I had a little idea... (sorry in advance for the photography- I was lazy with the set up and lighting, but I still think you get the basic idea).
The problem. I tried to sew the hole up from the back, but it just didn't look very good.
The solution. I got the embroidering thread and iron on kit on clearance at Target for under $2. Make sure you iron on interfacing onto the back if you decide to give this a try.
The finished product.
