Things You'll Need
Needle size 10
Cotton thread matching the color of the patch
Some dexterity with a needle and thread is all that you need to sew a patch on a hat. Patches, signifying schools, locations or emblems will look off-kilter if sewn on crooked, so pay careful attention to the initial placement. Use a fine quilting needle and a thimble for the sturdy patches. The right patch can add a touch of class or originality to any knit or fabric hat.
Place the hat on the wearer's head and determine the placement of the patch.
Attach the patch to the hat with white glue and let the glue dry for 30 minutes.
Thread the needle with 24 inches of thread. Place the thimble on the right hand middle finger, if right-handed, or left middle finger if left-handed.
Turn the hat to the wrong side. Knot the thread end and push the needle through the hat and patch with the thimble-clad finger.
Turn the hat to the right side. Sew small straight stitches around the edge of the patch.
