Once the first long border is done(side border), continue along the short edge (bottom edge): Ch 13, yarn over, skip 2 chains, insert the hook and pull up a loop.
Repeat this step a total of 3 times, then close all loops together.
Ch 3, make a sl st into the stitch where you created the puff stitch.
Ch 10, then make 1 sc along the edge.
(For better understanding, watch the video tutorial.)
Finally, crochet the last long edge the same way as the first.
Then finish the second short edge the same way as the first.
When this is finished, the scarf is complete – beautiful, lightweight, and ready to keep you warm during the coldest days of the year.
