That's a good thing.
But, it can also be a bad thing. Here's an example:
I finished off my openwork beanie design, above, with a final round of slipstitch. (So pretty!) After the pattern was published, a crocheter noted that the slip stitch round made her hat way too small. (So not functional!)
Since receiving that helpful feedback, I've been using single crochet or one of its variations -- such as back loop single crochet and reverse single crochet -- in my beanies' final round. (So much stretchier!)
