With a row of foundation single crochet stitches, you work a row of chains and a row of single crochet stitches at one time.
Begin with ch 2, leaving a 4 inch tail:
Stitch 1 – Insert hook into 1st ch, y/o and pull up a loop for the “chain” part of the stitch:
Then for the “single crochet” part of the stitch, y/o, pull up a loop:
y/o, draw through both loops on hook to complete the stitch :
I found that it helps to hold the “chain” while working the sc so that you can crochet the second stitch more easily.
Stitch 2 – Insert hook into the “chain” of the first stitch:
Y/o, pull up a loop for the second chain:
Hold the ch, and y/o, pull up a loop, y/o and draw through both loops to complete the second single crochet. This is what 2 FSC will look like:
And this is a row of 5:
When joining for a round, like when making an eternity scarf, you sl st in the “sc” part of the stitch, using the tail to attach the “chains”.
