To increase one stitch in single, half double, double or treble crochet, simply work two stitches in one stitch. For example, if you are working in single crochet and you need to increase one stitch, you would work one single crochet in the next stitch; then you would work another single crochet in the same stitch.
How do you widen a crochet blanket?
