Funny that we call this sewing, step 6 and we just pulled the machine out.

I didn't take a ton of pictures of actually putting it together, honestly they would just be pictures of fabric in the machine and you wouldn't really be able to tell what was going on anyway. Let's walk through this.

I started with the curves on the front shape, just folding them over and making a nice edge. Use an iron here if your fabric will allow it. Mine is shiny plastic and would melt, so I just went without the iron. Set that aside now.

The neck piece presented me with my first challenge with this project. I didn't want to have a visible seam and my sewing machine is kind of shitty. Maybe someone more skilled than me has a better way of doing this but I did what seemed to work, and it worked. First, I flipped it inside out and sewed the edges. Then(with my center marked) lined up the chest piece and sewed that on to one side of the neck piece. Still inside out here, I sewed the two halves together along the opening but left about an inch in the middle as a gap. Then I flipped it all right side out through that gap and very carefully closed the gap, staying as close to that seam as possible. In the end, if you get real close to it, you can see that there is about 2 inches of visible seam, but it is black thread and it it's incredibly hard to see because of how close to the seam it is.

The rest is fairly straight forward. Sew the bottom on the cheat piece, set that aside. Sew the two back pieces together, then line the sides up and sew the back to the front. Boom you have a top.

You could stop here, finish the bottom seam, and tell everyone that you made this awesome shirt from an Instructable you found. You would be praised highly, and given measurements from all of your friends asking you to make them one.
