The pattern does not make them ornaments (it doesn't have the loop of string to hang them), but that wasn't a hard fix. There are 2 options:
-Finish off as the pattern says, cut a piece of yarn a little longer than the loop size you want, and tie it to one of the points.
-Do not cut and finish off normally. Instead, when the last stitch is complete, cut the yarn several inches from the last stitch. Thread the yarn through the chains to one of the points. Once it's through the chain at the point, tie the yarn to itself close to the point.
I like the 2nd option because it's all the same thread and it looks neater and more stable.
It's a really fun pattern, and is right around the beginner level. You only need to know how to chain and single crochet. Just remember that once the initial loop is formed, the first round is done in the loop as a whole, not the individual chains that make up the loop.
I'd definitely recommend this for anyone who has a basic grasp of crocheting, especially if they are strapped for time and have extra white yarn lying around.
Have fun and a belated Merry Christmas!
