Here is a crochet pattern for a retro tie up head wrap. The two ties are knotted in a square knot with the rounded ends extending out on either side. The knot may be worn on the top of the head, to the side or even in the back. The ridged or ribbing pattern adds extra interest.
Four sizes are included: baby, toddler, child/teen and adult.

If you like a retro, vintage look or want something to wear during a workout, this is an easy pattern. Make one for yourself or as a gift.

Make it out of cotton yarn for summer wear, acrylic or wool for cooler weather. Medium weight, size 4, worsted weight is called for.
