A technique that for larger projects uses a long crochet hook, called an Afghan hook. Start with a row of chain stitches. Work first row by inserting the hook back into the second chain from hook, pull yarn through, then insert hook in next chain, pull yarn through and so on until end of chain row.
All new sts remain on the hook and at the end, there will be as many sts on the hook as the pattern required. Do not turn work, but now start binding off each stitch by first pulling yarn through 1 st, then yarn trough 2 sts at the same time until end of row. Make sure to have a constant number of sts every time you pick up new sts. This technique creates a dense fabric in a grid pattern with a definite front and back side.
