These are so cute! It's a great way to remind people to be safe - or to designate your personal space!
This is a great pattern for a crocheter who already has a good grasp on the basics. Some sewing knowledge and possibly embroidery can help, but are not required.
The pattern is a five-page PDF file with handy pictures to refer to. It is not a tutorial. If you do not know how to crochet, you will not be able to make this pattern.
