This rose is a nice 3-dimensional flower that can be used as a corsage or in a bouquet (or vase). It is a simple 3-row pattern consisting of single crochet, chains, and double crochet stitches.

The leaf is made by crocheting on both sides of the chain using basic stitches like single crochet, half double crochet, and double crochet.

There is a step-by-step tutorial video for this pattern.
