Take a box of spindles--each used for spinning silk. Every spindle is unique with different weights for spinning ability. These are all under 1 ounce.
Once your spindle is full, wind the silk off into small balls and store. All fiber, whether spun or unspun, needs to age properly before usage! For me, these little balls of silk are so finely spun (machine thread fine) that it takes at least 4 ply to make a yarn that is knitable.
Ply together--doesn't matter what the colors are--it blends. Below is the result of knitting small squares and large squares.
Here the squares are laid out on the carpet to block and below are squares joined together. If you want the complete pattern, check out Spring 2008 issue of Interweave Knits page 102 Chameleon Scarf by Lorilee Beltman or purchase from Ravelry as Holey Scarf.
And here is the finished scarf.
