Hair Bows from trouser or knee length nylon/spandex socks. I have found that the smooth print socks are woven tighter and therefore have better stretch recovery than some others that have a textured weave to them.
Using a straight edge, or pair of scissors, trim off the toe seam and ribbed calf portions. If you want a wide bowband then stop here. Turn sock right side out, overlap ends, and hand sew just like with the nylon band instructions. For thinner bands continue to the next step.
Measure the middle of the sock witdth and using a straight edge cut into 2 equal width parts. Mine were about 1.75" wide.
Don't worry if it shifts a little and your raw edge isn't even. You can trim that after your seam is sewn.
Turn your band inside out and finger press the seam. You may have to roll the seam between your fingers to get it to smooth out. Now you're ready to overlap your short ends and hand stitch as before. Make sure your seam is to the side and not running down the middle.
Cover the scrunched seam with ribbon as before making sure to heat seal your ends.
Finished! Attach your favorite clip to the front and enjoy!
