Foundation Chain

 A foundation chain is often used to start a flat piece or an oval piece, beginning with a slip knot.

 HOW TO COUNT CHAIN STICTHED?
 Each chain stitch makes a ""V"" shape. Count the number of V's to count the number of  chain stitches you have.
 It's also important to keep in mind that when you're counting chain stitches, you shouldn't count the slip knot that you made at the beginning of your chain as a chain stitch.
 Here’s a chain with 13 stitches in it. I’ve called out the second chain from the hook, because if you’re making the next row with single crochet stitches, the first stitch you make will be in the second chain from the hook. This is because the chain that you skipped gives the first single crochet stitch its height.

TIPS:

Twisting: Minimize the chance of twisting your chain by constantly moving your left hand to hold the chain as close as possible to the hook.-Consistency:

Tension: Ensure each chain stitch is the same size for a uniform foundation.
 Keep an even tension in your yarn to avoid tight or loose stitches.

Count: Periodically count your stitches to ensure you have the correct number for your pattern.

Creating a neat and even foundation chain sets the stage for the rest of your crochet project. Practice makes perfect, so take your time and enjoy the process!
