Narrowing (dropping stitches)
Narrowing the work at the edge of the crochet piece requires the closing of the edging stitches or dropping the last stitch, as shown on the featured picture.
In single crochet stitch, you need to crochet one chain stitch at the beginning of the row (turning chain), then insert the crochet hook into the second stitch of the previous row and crochet a slip stitch from the loop lying on the hook. Crochet single crochet stitches as normal until the end of the row and repeat, following turning over the piece.
In order to narrow a piece of crochet in a double crochet stitch, you need to crochet two chain stitches at the beginning of the row instead of a double crochet stitch (turning chain), insert the hook into the next stitch of the previous row, and crochet an unfinished half double crochet stitch. We have two loops on the hook. We yarn over the thread and draw it through these two loops, yarn over once again and pull it through three loops. We crochet the row until the penultimate double crochet stitch. In the penultimate stitch we make an unfinished half double crochet stitch while in repeating this in the last stitch.
