Fishnet is a knitted or woven pattern that resembles the mesh nets used to catch fish. Most often associated with stockings, fishnet is actually useful for several different purposes. A basic fishnet knitting pattern can be used to create scarves, sweaters and even table cloths. If you are familiar with basic knit and purl stitches and can do a yarn over increase, that's all you'll need to know to knit fishnet.
Cast 40 stitches onto one of the knitting needles.
Knit across the entire first row.
Wrap yarn over the left needle (the "working" needle) then knit two stitches together. Repeat this pattern of knitting one, wrapping yarn over and then knitting two together all the way across the second row. Knit the final stitch left at the end of the row.
Knit one, purl across the row and knit the final stitch at the end of the row.
Continue these two steps of the established pattern until the piece is as long as you want it to be.
Bind off across the row and cut the yarn leaving a 2-inch tail.
Weave the loose end of the yarn into the edge of the piece using the tapestry needle.
This pattern can be increased using multiples of four. You can make a piece as big as you need to or incorporate it into any other pattern (like a sweater) as long as the stitch count is divisible by four. The weight of yarn used can be lighter than worsted weight. If you want to use a lighter weight of yarn, decrease the size of needles to size 5 or 6.
