You can make this in as many sizes as you have yarn to crochet! The scarf shown is the smallest size recommended at 114 chains across.
This pattern is in the EASY category. a Half Double Crochet is the same as a double crochet except after the yarn over, you pull the yarn through all 3 loops. The pattern is written so you can add the “Lace” details by making a row of Double Crochet’s and chain stitches across. They can be saved for your second scarf if you are worried about difficulty.
Most of all, have fun!
