First you will need some yarn and a crochet hook.
Then you make a knot with the crochet hook and start doing the basic crochet stitch or braid. You can make it as long as you want your scarf to be; I made about 280 stitches because I like long scarves.
Once you have figured out the length that you want it, make 2 more stitches.
Then you put the yarn over the hook and slip it in the last stitch before you made the 2 extra stitches.
Make as many rows as you want your scarf width to be ( I made 12 rows on mine)
This is the finished scarf...You can leave it like this or make a fringe if you like.
To make the fringe, cut strands of yarn as shown on the picture
Take 3 of the strands and put them in through the 1st two holes at the end.
Put the strands through the loop and pull; Repeat for the other holes
This is what the completed scarf looks like with the fringe.
Here are some other scarves I've made.
