A common way of decreasing the number of stitches on a row is to knit two stitches together (K2TOG) … this decreases the number of stitches on the row by one stitch every time.
But you can also make multiple decreases by knitting 3 stitches together … this decreases the number of stitches on the row by two stitches every time.
The knitting pattern may give you instructions on how to make the decrease, so do follow these if they are provided. If your pattern does not give instructions, the technique in the tutorial below gives a balanced decrease, as shown in the sample. The centre stitch of the decrease lies on top, and the knitting slopes at either side.
Here are the steps to make this decrease ….
Step 1: Put the tip of the right hand needle knitwise into the second and then the first stitches on the left needle (as if you were going to knit 2 together).
Step 2: Slip the two stitches onto the right hand needle.
Step 3: Knit the next stitch on the left hand needle as normal.
Step 4: Lift the two slipped stitches on the right hand needle over the knitted stitch on the right hand needle.
I hope this is a helpful tutorial
