If you need a last-minute gift, or you just want to add a new flair to an old wardrobe staple, crochet a flower brooch for yourself or a friend. If you have a basic understanding of crocheting in the round, you can crochet a flower brooch in an hour or so, and wear it with pride for years. Use up your leftover yarn scraps from other projects to make a crocheted flower brooch in a variety of colours and styles.
Choose your materials. If you make a crocheted flower, let the yarn dictate your project for you. Use worsted-weight yarn and crochet hooks in sizes US-G, I, and K for a layered flower. For a small or lacy flower, use fingering weight or lace weight yarn or even cotton crochet thread with a small hook, approximately a size US F. will also need to find some type of pin to sew onto your brooch; craft stores sell packages of pin backings for a few dollars. Find a spool of thread to match your yarn and you will be ready to crochet your flower brooch.
Begin with the smallest flower, using worsted weight yarn and a size US-G hook. Make two chain stitches and then make five single crochet stitches into the second chain from the hook. Join with a slip stitch, chain one, and make two single crochet stitches into each stitch around, for a total of 10 single crochet stitches. Join with a slip stitch.
Form the petals of the flower. Chain three, then make two double crochet stitches into the next stitch. Chain three and slip stitch into the following stitch. Repeat this four more times, for a total of five flower petals. Fasten off, cut your working yarn, and make a slip stitch to secure it. Leave the ends loose for now.
Crochet two more flowers just like the first, but with different hooks. For the second flower, use a size US I hook, and for the third use a size US K hook. Use the same yarn for all three flowers. Now you will have three identical flowers in different sizes.
Use a needle and thread to sew the pin backing onto the back of the largest flower. This way you will be able to hide the thread stitches behind the other two flowers. Use your large-eye blunt needle and your loose ends to sew the three flowers together, the smallest on top of the medium and the medium on top of the large. Now you have a three-layer flower.
Use a scrap of leftover green yarn to crochet a leaf. Chain four, and single crochet in the second chain from the hook and each chain across. Chain one, and make one single crochet in every stitch across. Chain one and make two single crochets in every stitch across. Chain one and make one single crochet in every stitch across; repeat this row two more times. Chain one and single crochet two stitches together all the way across. Chain one and single crochet in every stitch across. Chain one and single crochet three together. Cut your working yarn and make a slip stitch. Repeat for a second leaf, and sew them to either side of your flower, slightly overlapping the petals onto the leaves. Weave in any extra loose ends on your flower brooch; now it is ready to wear.
