TECHNIQUE CRAFTS 🎨✨
Secure the thread and bring the needle to the surface at the position of the button, then bring it through the button from the back.
Take the needle down through the other hole and through the fabric leaving a small gap between the button and the fabric.
Repeat the above to work a few stitches through the button holes, take the needle around the threads between the fabric and button to form a shank.
To finish work on the wrong side and make a couple of stitches through the treads secure.
