Gather your supplies. Working on a flat surface is helpful if you are new to crocheting or using ruffle yarn. Scissors is only needed if you are using part of a skein.
Roll about 2 feet of yarn off of the ball. Stretch it out with the decorated side toward you.
Tie a knot at the end of the yarn to keep it from unraveling. Tie as close to the end as you can so you do not waste yarn.
You are going to crochet into the top row of holes.
Find your first hole.
Insert your crochet hook into the first hole from front to back.
Bring the hook to the front through the next hole.
Repeat the in and out with the next two holes.
Put your hook into the 5th hole. Now using the hook, grab the top of the 5th hole.
Pull this loop through the other holes.
Only the loop from the 5th hole should be on your hook.
Now repeat those steps. "In, out, in, out, grab and pull."
Each time you repeat these steps you should end with only one loop on your hook.
Remember to keep unrolling and stretching out the yarn as you go.
After you have done this a few times you will start to see your ruffle forming.
When you are 6-12 inches from the end, stop and tie a knot at the end of the yarn.
Finish crocheting to the end.
Pull the last loop through to make a large loop by the knot.
Pull the knot through the last loop
You now have a ready to wear ruffle scarf.
