There's something fishy in my pocket!

Step 2 The tail end.

Start at the tail end and cast on twelve stitches and knit one row plain and one row purl. If you want a wider, longer tail, start with a few more stitches (multiple of two) If you want a very wide tail, but not a longer one. Cast on 24 stitches and decrease one stitch at each end of every row.

Knitting tip, When not increasing or decreasing, I always slip the first stitch at the beginning of the row, instead of knitting as this makes a much neater row end.
