Since I didn't want to worry about matching fabrics, I made this shirt from scratch. I am sure it would have been a lot easier if I had found a t-shirt and matching knit fabric. I used a shirt that I knew I liked the fit of as my pattern. I cut all the pieces (front, back, sleeves) from this fabric. I wanted short sleeves instead of long sleeves, but it would be easy to make it with long sleeves too.
Before sewing any pieces together, I worked on the back of the shirt. I cut slits horizontally about an inch and a half apart. You could do wider if you want. Make sure you don't go too close to the top or bottom. The back gets heavy once you add the weave into it. Next, cut strips from the extra fabric that are about an inch and a half to two inches wide. These will get woven vertically. I then put a stitch at the top of each "over" piece to keep it in place. Originally I did not do this, but I didn't like how bunchy it got. I like a lot of random, but it was a bit too much even for me. Now it feels a little more structured.
Next, sew all your pieces together - front to back, then add sleeves. I added a band at the bottom to the shirt just to add a little more. Easy as that, right?! I love projects I can do in one day with materials I have at home!
It was a little windy when we took these pictures, but you get the idea of the shirt!
