How to Make a DIY T-Shirt With Flannel Sleeves in 6 Simple Steps

Tools and materials:

• T-shirt
• Flannel
• Scissors
• Fabric marker
• Pins
• Sewing machine

1. Mark the shirt 

Place the ruler on your t-shirt right before the seams of the arm. Then draw a straight line going all the way down the shirt to the hem. Repeat on the other side.

2. Cut out the middle

Follow the line you created and cut out both sides of the shirt. The graphic should be in the middle of the shirt and the shirt should be just missing the arms.

3. Cut out the sleeves of the flannel

Use the squares of the fabric of the flannel as a guide, and cut a straight line through both layers about an inch before the arm seams start. Do this for both sides.

We’re going to be replacing the middle fabric of the flannel that you just cut out with the middle of the graphic t-shirt. 

4. Turn all of your fabric inside out

Before we sew, make sure you turn the t-shirt middle and the flannel sleeves inside out and right sides facing.

5. Pin the flannel to the t-shirt

Take the shoulder seams of the t-shirt and line them up with the shoulder seams of the flannel sleeves and pin them right sides facing. 

Continue to pin all the way down the shirt with everything right sides facing.

6. Sew the flannel to the shirt

Once everything is pinned, use a zigzag stitch to sew the fabric together. Make sure to back tack at the start and end of each line you sew.
