This is such a sturdy bag and it is super easy to make!
Step 1: Cut the Shirt
Cut the shirt like you are cutting a tank top.
Step 2: Cut the Bottom
Now just cut straight lines at the bottom of the shirt.
Step 3: Tie Knots at the Bottom
Take random strips at the bottom of the shirt and tie them together in double knots. This will prevent whatever you put in the bag to fall out.
Step 4: Finished!
And your done! Enjoy your sturdy bag!
