I have seen all kinds of different ways to make pom-poms. This is how I make mine when I need a specific size. I usually use my hand to make a pom-pom. But no not today, folks. Here is want you will need, Scissor, yarn( the thicker the yarn the thicker the pom-pom) manila folder (or thicker paper) something to measure with and a pencil.
Step 1: Mark the card
I measured five inches in height and three inches wide. So that gave me a 3 by 5 card. The pom-pom will be three inches once done. You can choose the width of the card to make any size pom-pom. The length is just something to hold on to when wrapping the yarn. Just play around with the measurements until they fit you. Just be sure to mark to center point on both lengths I also marked the center point in between the three inches at 1.5 and the five inches at 2.5.
Step 2: Cut out the card
Ok, now you will cut out the card and cut up the center of the shorter side, up to the center point of the longer side. Take a piece of yarn about 8 to 10 inches long and side both ends through the slit of the card.
Step 3: Make it fluffy!!
Wrap your yarn around the card until it's the thickness you want. The more you wrap it the fluffer it'll be. Next take the 8 to 10 inch piece of yarn and tie a knot around the wrapped yarn.
Step 4: You now have a fluffy pom-pom(:
Slide the bundle of yarn off and cut the loops on both sides. Fluffy it out and now you have yourself a fluffy pom-pom.
