Flutter sleeves on Classic T-shirt

Flutter Sleeves

If you want to change your look using a user-friendly classic pattern, this hack is for you. After making the tank version of the Classic T-shirt, I was ready to try something different. I chose flutter sleeves because one of my favorite handmade shirts has flutter sleeves, and the silhouette looks great. Although this is a simple hack, it completely changes the overall look of the shirt. While it is still a casual top, it can easily be a transition piece, depending on what you pair it with. It looks cute with jeans or shorts as well as dressier pants or a skirt.

Creating a new pattern piece
Step 1: I found my old flutter sleeves shirt pattern and created a similar sleeve pattern piece. I accomplished this by tracing around the old pattern piece on top of the sleeve pattern piece from the Classic T-Shirt. Then, I adjusted my lines and curves.

Step 2: I cut out the fabric and checked to make sure the size would fit with my Classic T-shirt main body section. Luckily, it worked rather well.

Step 3: Next, I made a narrow hem on the outside edge of the flutter sleeves. Also, I made sure to use a flexible stitch, so that the material flows freely instead of looking stiff.

Step 4: After completing the narrow hem, I attached the sleeves to the shoulder and rest of the arm hole of my Classic T-shirt. I placed right sides together and sewed a 3/8″ zigzag stitch, making sure to overlap the tails of the flutter sleeves at the bottom of the arm hole.

Step 5: For finishing purposes, I also pressed the seam allowances toward the body of the shirt and then top stitched, which looks more polished. That’s really all I had to do! It was quick and easy, but it made the shirt look drastically different from the basic short sleeve Classic T-shirt.
