Increase 1 stitch at beginning and end of row

Increasing in Knitting

There are three main methods of increasing stitches, all of which are quite simple to do. The first is to make a stitch (M1) by picking up a loop between two stitches and knitting into the back of it.

This forms a neat, invisible increase, so is often used in the middle of a row or where a series of increases are to be worked.

The second is to work into the front and back of a stitch (inc 1 or inc in next st). This method is normally used at the beginning and end of a row, for instance on sleeve shapings.
The third method is to make a yarn forward increase (yf) which, when completed, leaves a visible hole and is often used in lacy patterns.
Don’t confuse the ‘M1’ and ‘inc’ methods of increasing.

For example, after the rib has been worked, instructions are often given in the next row to increase stitches across the row by the ‘make one’ (M1) method. This does not use up a stitch but if you increase by knitting into the front and back of a stitch each time your instructions will not work out
