Finger knit approximately 8 rows (6 inches or so). If you run into the bells as you go, continue to push them down the strand of yarn towards the ball.
Bring the bell and the strand over your finger, as you normally would.
The bell should settle into the middle of your finger knitted strand. Then, continue another 16 rows or so before you place another bell. Continue to place another bell every 16 rows until the strand reaches your desired length.
It should look like this at the end. Make sure it is long enough to stretch most of the way across your door frame.
Make the Curtain
Decide on the pattern of strands. Lay them out.
Weave each strand of finger-knitting under and over a row of finger knitting in the valance.
Turn the strand at the top, and come back down the next row, weaving in the same manner.
