When you get to the end of your crochet design and you’ll need to fasten off the yarn. Fastening off crochet is a fancy way to say “cut the yarn and secure it.” You also need to fasten off one color to join a new color if you’re working with different color yarns.
Cut the yarn about 6 inches from the hook.
You weave the yarn end into the fabric to secure it.
Using your hook, draw the cut end of the yarn through the last remaining loop on your hook.
This step actually fastens off the yarn.
Pull gently on the tail of yarn to snug up the end.
This action keeps your work from coming apart without having to make large unsightly knots.
Thread the remaining yarn tail onto a yarn needle.
You need the yarn needle to weave the yarn into the fabric.
Weave the 6-inch tail of yarn up and down through 3 or 4 stitches — kind of in a zigzag pattern.
Be careful not to split the yarn of the stitches.
Go back the way you came, weaving the end backwards through those same few stitches.
This step makes the end really secure.
Cut the yarn about 1/4 inch from the fabric and gently pull the fabric.
The end disappears like magic, and your work is secure.
