It's that simple:
Download the template for this scarf
The front of the scarf is made of fleece, the back of fleece. Of both fabrics you need one Fabric cut each of 33 x 135 cm size. As closure you use an approx. 70 cm long Cord (paracord cord)
Fold the fabrics together to the left, fix the Cord and sew the edges of the scarf, taking into account a turning opening as shown on the template.
Turn the scarf and sew the opening. Now position the eyelet and press it into the corner of the scarf using the eyelet-hole tool.
Extra tip: To prevent the eyelet from tearing out of the scarf, you can reinforce this area with fleece before turning it over.
