Finger knitting is exactly what it sounds like. Instead of using needles to create knit stitches, you use your fingers. This is an inexpensive, easy-to-master craft for children, but even adult crafters use strands of finger weaving to make anything from skinny scarves to purse straps and, if you're willing to stitch multiple strands together, blankets. In general, finger knitting gives the best results when done with a bulky yarn or several strands of thinner yarn held together.
Drape the yarn across the front of your nondominant hand, so the ball end runs across the heel of your hand and the tail end drapes across the space between your thumb and first finger. The tail should be at least six inches long, making it easy to weave the loose end into the finished project.
Pull up about a foot of slack from the ball of yarn. Wrap the yarn across the front of your index finger, behind your middle finger, in front of your ring finger and behind your smallest finger. Apply only light tension to the yarn as you wrap it.
Wrap the yarn behind your smallest finger, then bring the yarn around that finger to the front of your hand. Work back across your hand, wrapping behind every other finger -- this time, the yarn goes behind your ring finger, in front of your middle finger and then behind your index finger. "Turn the corner" again, wrapping the yarn around your index finger until it lays across the front of your hand.
Work across your hand one more time, making each wrap slightly higher on your fingers than the previous wraps. The yarn goes behind your middle finger, in front of your ring finger and behind your smallest finger. You should now have two wraps of yarn around your index and ring fingers.
Gently tug the bottom loop of yarn around your index finger up and over the top loop, until the bottom loop slides off that finger to rest against the back of your hand. Repeat with the bottom loop on your ring finger.
Wrap the yarn from the pinky finger side of your hand back to the index finger side of your hand. This time you have two loops on your smallest finger, and two loops on your middle finger. Pull the bottom loop on each finger up and over the upper loop, until it slides off your finger and rests on the back of your hand.
Continue working back and forth across your hand, stopping at every pass to slide the lower one of any paired loops up and off the back of each finger. Your finger knitting will accumulate in a flat chain down the back of your hand.
Tug on the chain periodically; this stretches it into its finished shape. Once the chain/tube is as long as you want it, clip the yarn about a foot from the end of your project. Slide each loop off your fingers onto a crochet hook, then use the hook to draw a bight, or loop, of thread through all the finger loops together. Run the tail end of the yarn through the bight you just made and pull it snug to complete the bind off.
If you struggle to keep the tail end of the yarn in place as you take your first few "stitches," tie it loosely around your thumb. For an alternative binding off technique, drape the loose end of the yarn between your thumb and forefinger. Transfer the finger loop from your smallest finger to your ring finger. Slide the lower of the two loops -- the original ring-finger loop -- up and off your ring finger. Transfer the remaining loop to your middle finger and repeat until you're left with only one loop; then run the loose end of the yarn through this loop and pull until it's snug.
