This video knitting tutorial will help you learn how to knit the make two double increase (m2). This technique of adding stitches to share your knitted fabric uses a similar method to the stranded or lifted increase. It allows you to increase twice in-between stitches, which can be useful in top down hats and shawls.
Work your pattern until you reach the stitch where you want to increase.
Step 1: Insert your main needle into the strand in-between the stitches where you want to increase, going from front to back.
Step 2: Insert your working needle through the back loop of the strand on your main needle.
Step 3: Knit the stitch.
Step 4: Pull the stitch of the main needle.
Repeat this sequence once more using the same strand.
