Here is the crochet cowl I was making:
It’s not the neatest piece of crochet ever, but it was good to practice stitches with. The pattern is Crochet Class Cowl by Jennifer Dickerson. I decided to add the edging to make it look a bit neater, but I’m not sure this worked! I think if I did it again I would have changed the number of stitches when the type of stitch changed to make the edge less wavy and untidy, but the untidiness probably has less to do with the pattern and more to do with my lack of experience in crochet!
