Choose the button type and thread color
Thread a needle and tie a knot at the end
Mark or position the button on the fabric
Push the needle up through the fabric at the attachment point
Pull the thread through until the knot sits flat against the fabric
Sew the first stitch through the button holes and back through the fabric
Repeat through the button holes several times (about 6–12 stitches)
If using a shank, place a toothpick/thread spool between button and fabric while stitching
Keep stitches tight and evenly spaced
Finish by bringing the needle back through the fabric near the last stitch
Tie off: pass the needle through a few existing stitches, then pull tight
Cut the thread close to the fabric
If needed, secure with a couple of extra knots and trim neatly
