So in full disclosure, I did not go in to making this shirt with the intentions of it being a Fourth of July shirt, but it happened that way, so we're going with it.
(I apologize in advance for the blueness of all these pics, wasn't paying attention to the fact that the carpet is also blue in the sewing room)
What You Need:
1) A Shirt (One that is a little big on you will work best)
4) Scissors/Exacto knife
5) Studs (I actually am using star shaped brads)
First, using a ruler draw a straight line with the chalk across the front of the shirt. I made mine right where the V on the neckline exists.
Then, also using a ruler, draw vertical lines from the shoulder seam, down to the horizontal line you drew. I made 10 lines. I wanted 8 strips, so 10 lines.
Cut down all of the vertical lines you just drew. DO NOT yet cut the horizontal line. I used an Exacto for this as it is easier, for me personally, to do that than cut in with scissors. But that is up to you. If you do use an Exacto, make sure to have a cutting mat below, and PLEASE BE CAREFUL. I have seen (and experienced) too many Exacto accidents to not stress that.
Use the Brads, or studs, to connect every other strip you just made. Once you can see which strips you will actually be using, cut out the ones you don't. This part is a little hard to explain, but basically in the end you will only keep every other strip.
Use as many Brads as you like, and connect the strips in whatever pattern you feel like.
Finally cut a slit in the bottom of the shirt along the side. And tie the slit on the side.
That's it! I may pair this with a red tank underneath just to make it extra patriotic.
