Crochet roses are amazing and can be used for so many different purposes. I am partial to using sock yarns and embroidery floss for my smaller roses.
A great way to display these pretty things is to create a Rose Ring. You can buy the ring bases at any craft store for a few dollars. There are usually multiple rings in a pack so you can make Rose Rings for your friends as well.
The quickest way I have found to attach the finished roses to the ring is with a hot glue gun.
Total time to make a ring: 20 minutes for the rose. 2 minutes to glue it to the ring base. Ta Da!
