Approximately 470 yards of lace or sock weight yarn (pictured: Malabrigo Lace in Alpine Pearl).
Size US 4 needles. Using a US 4 produces a dense fabric. If you prefer a lacier fabric, feel free to use a large needle.
Experiment with a few sizes and choose whichever you feel looks best!
Note: If you choose lace weight, you will be holding two strands at once while knitting (If using one skein of lace weight, make sure to have the ball wound so that both the center end and the outside end can be used simultaneously. Most yarn shops have a ball winder that will accomplish this for you).
If you choose a sock weight yarn, you will be using one strand while knitting this pattern.
