If you can crochet in the round, you can crochet a bucket hat. A bucket hat has a looser-fitting crown and a wide, all-around brim, making it ideal for warm-weather days when you want to shade your eyes from the sun. Use a cotton yarn to allow your bucket hat to remain cool on the hotter days. Once you learn the basic instructions to crochet a bucket hat you can make several more in a rainbow of colors.
Chain four and join with a slip stitch to form a circle. Chain three; this stitch will count as one double crochet stitch here and throughout the pattern. Make nine double crochet stitches in the circle and join with a slip stitch to the top of your initial chain-three stitch.
Chain three and make one double crochet in the same spot as the turning chain, then two double crochet stitches in every stitch around. Join with a slip stitch.
Increase your circle until it is approximately the same circumference as the head of the person who will wear the hat. To do this, chain three and make one double crochet in the same stitch as the chain stitches, then one double crochet in the next stitch. Make two double crochets in the next stitch and one double crochet in the stitch after that; repeat this pattern around, then join with a slip stitch.
Increase round four by making a chain-three stitch and a double crochet in the same stitch; then one double crochet in each of the next two stitches followed by two double crochets in the third; repeat this pattern around and join with a slip stitch. Continue to increase, each round adding one more individual double crochet stitch before the two-in-one double crochet stitches.
Chain three. Working in the back loops only in this round, make one double crochet stitch in every stitch around. Remember that your initial chain-three counts as your first double crochet stitch. Join with a slip stitch.
Chain three and work one double crochet stitch through both loops of every stitch around until the hat is tall enough to rest comfortably on the wearer's forehead.
For the next round, work in the front loops only for every stitch around to begin the brim. Chain three and work one double crochet in the same stitch as the starting chain. Work six individual double crochet stitches followed by two double crochets in one stitch; repeat this pattern around. Make at least two additional rows, starting with a chain three and each time increasing by one the number of individual double crochet stitches between the two double crochet stitches worked in one stitch. When the brim is as deep as you like, fasten off and cut your working yarn. Weave in all loose ends with a large-eye blunt needle.
