The Single Crochet Thermal Stitch is a variation on the basic Single Crochet that we all learned when we were first starting out. The unique thing about this stitch is that it gives you a double layer of single crochet stitches, which are all worked at the same time.
The result is a super thick, durable fabric that can be applied to so many projects – think hot pads, oven mitts, even the base of a basket or purse if you want something really strong and thick.
Single Crochet Thermal Stitch Tutorial
Row 1: Chain any number. Starting at the second ch from hook, work 1 sc into the bottom loop of each chain st (This bottom loop is important!), ch 1 and turn.
Row 2: *Insert hook into the back loop of the first sc AND the parallel loop of the chain row below. Work 1 sc as normal. Repeat * for each st across, ch 1, turn.
Row 3: *Insert hook into the back loop of the first sc AND the parallel loop i.e. the missed front loop of the previous row. Work 1 sc as normal. Repeat * for each st across, ch 1, turn.
Row 4-n: Repeat Row 3 for the required number of rows
Final Row: Insert hook into both loops of the first sc AND the corresponding parallel loop. Work 1 sc as normal and repeat for each st across.
Note: Be careful not to skip the very last stitch in each row – it can be tricky to find!
