Ready to make your very own DIY flannel t-shirt? Let’s get started!

Tools and materials:

  • T-shirt
  • Flannel
  • Scissors
  • Fabric marker
  • Pins
  • Sewing machine
Marking the graphic t-shirt

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.

Cutting out the middle of the graphic tee

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.

Cutting the sides and sleeves of the flannel shirt

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.

Placing the middle of the t-shirt between the flannel 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. 

Turning the fabric inside out

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.

Pinning the flannel sides to the t-shirt

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. 

Sewing a flannel t-shirt

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.

    I think it would look prettier if u just cut the front of red shirt

      I'm not understanding your idea? Cut the front of red shirt, and then what?? I personally have so many T-shirts with wolves, country, and some of them with wonderful words written about the town's where I purchased them, (summer vacations all across the United States) and now I need to buy the flannel shirts to do this idea, I just LOVE it!

    I love this idea, especially for tshirts and flannels that I’ve out grown but love. Put the two together and you have a better fitting unique shirt. Thanks for the inspiration
