Final result ... Use any yarn that you are comfortable with and its recommended hook size. If you don't have split ring stitch markers, you can use paperclips, safety pins, or scraps of yarn.
Supplies -Any Size Yarn - Crochet Hook - Split Ring Stitch Markers
Begin with a slip knot on your hook.Grab the yarn with the hook and pull through the loop on the hook to chain (ch) one.
Ch 1 again. This counts as the first single crochet (sc) and its foundation chain.Insert the hook in the second (farthest) ch from hook.
Pull up a loop. (2 loops on hook)Yarn over, pull through one loop on the hook. (2 loops on hook)
The chain stitch just made by pulling through only one loop is the foundation stitch for this sc. It is also where you will insert your hook to begin the next stitch. To help you find this stitch, place a stitch marker now.Yarn over, pull through both loops on the hook to complete the sc. (1 loop on hook)
Insert hook in the marked stitch.Pull up a loop. (2 loops on hook)
Yarn over, pull through 1 loop (2 loops on hook). Place a stitch marker in the chain just made.Yarn over and pull through both loops on the hook to complete the sc. When you are ready to practice without stitch markers, you can find the foundation chain by counting to the third loop from the hook. Starting after the loop on the hook, there will be two horizontal bars, then the loop to insert your hook.
With practice, you'll be able to remove the stitch markers. If you notice a bump or "ripple" in your row of Fsc, check the base of the stitch. When you stop using markers, it's easy to forget to make the foundation chain for the stitch when working quickly. A bump such as this one means you made two stitches in the same foundation stitch. Back up 2 stitches and correct the stitch.The Fsc eliminates the possibility of chaining an incorrect number of stitches for a large project and the frustration of working into the starting chain. The foundation chain at the bottom of each stitch provides a symmetrical beginning chain for working in the round or adding borders. This stitch also creates a stretchy starting chain, making it useful for items such as garments and headbands.source
