K3tog (knit three together) is a double decrease and is exactly as it sounds…….you knit 3 stitches together, decreasing your total number of stitches by two. It is just like making a regular knit stitch but you work through three stitches instead of one.
How to work a K3tog decrease
So I have cast on 10 stitches and worked a few rows in stocking stitch, on the next knit row the instructions are :
Knit to last 4 stitches, K3tog, K1. (8 sts)
I have knit to the last 4 stitches of the row and am now ready to work K3tog:
Step 1 – Insert the right hand needle through the next three stitches on the needle, from front to back (as you would if you were knitting a normal stitch).
Step 2 – Pass the yarn around the back, up and over the front of the right hand needle (as you would if you were knitting a normal stitch).
Step 3 – Pull the yarn through the three stitches, slipping them off the left hand needle.
A double descrease completed.
