These covers are fast and easy and so cute.  They do fit snuggly. I usually decorate the jar also. I glue ribbon roses to the center and I thread ribbon around the neck of the jar through the hdc stitches. You can vary things by crocheting in back loops only or front loops only or both loops like I did. Use your imagination.  You can do these in Christmas colors to give away your homemade goodies or put bubble bath and different items in the canning jars.
