Made to measure. The finished scrunchie is roughly 4” across.
The difficulty is listed as ‘easy’, but is achievable by anyone familiar with the following techniques:
joining/crocheting in the round, changing colors, carrying floats, and whip stitch.

Materials:
• About 20g or 75 yds of any DK weight yarn
• 3.5 mm hook
• 1 stitch marker
• Scissors
• Tapestry needle
• Ruler or measuring tape
• An elastic hair tie (I use seamless ties that stretch comfortably to a 16” circumference)
