If a pattern starts with chains followed by single crochet, it is possible to combine these two steps.
Foundation single crochet (FSC):
Begin with a slip knot and chain 2.
Insert your hook in the first “V” – yarn over hook and pull back through the “V” – you now have 2 loops on your hook .
Yarn over hook and pull through 1 loop.
Yarn over hook and pull through both loops.
Continue step 2 & 3 till you have the required number of stitches.
