I used Bulky yarn and size L (8.0mm) Crochet hook
Make a chain of 15, now single crochet (sc) in every chain across. You should have 14 sc stitches at this point.
Chain 1, sc across in the back loop of each sc to the end, Continue with every row the same. Crochet till the scarf is about 26-34″ long or as long as you wish. Now twist once to make the mobius then crochet the two ends together. Weave in ends and you are ready to wear it! You can make the scarf wider if you like, or change the yarn to worsted weight yarn and add more chains at the beginning. (Don’t forget to make adjustments accordingly.)
If you are not interested in making this scarf but would still like to have one, you can buy them ready to wear at my Etsy shop, trimitup.etsy.com They really make a nice gift.
Please let me know what you thinks, and if you make it, let me know how it turns out!
Happy knitting (crochet) marilynknits
