Crown
Step1
Chain 87, make 1 single crochet in the second chain from the hook, and continue with 1 single crochet in each chain to the end of the row. Chain 1, turn and single crochet to the end of the row.
Step2
Chain one, turn and single crochet the next row. Continue turning and working in single crochet until the piece measures 3-1/2-inches high.
Step3
Do 6 single crochet, then 1 decrease stitch. To decrease, insert the hook into the next stitch, draw up the loop, insert the hook in the following stitch as well, yarn over and draw the yarn through three loops.
Step4
Work 8 more single crochet and then 1 decrease stitch. Continue working a pattern of eight single crochet and 1 decrease stitch to the end of the row. You should have a total of 78 stitches at the end of the row.
Step5
Begin with six single crochet and one decrease stitch, followed by seven single crochet. Work the rest of the row with seven single crochet followed by one decrease stitch. This gives you a total of 70 stitches in the row.
Step6
Crochet the next seven rows by starting each row with six single crochet, then continuing to decrease the number of single crochet between each decrease stitch by one. After working seven in this way, you end up with a row of 14 stitches.
Step7
Finish the crown by doing two decrease stitches, a single crochet, and then alternating between a decrease stitch and a single crochet for a total of six stitches. Fasten off, leaving a long piece of yarn. Gather the top stitches together and sew the seam with this yarn.
