This is a very easy garland that I made for some Valentines decor in Scarlett's room.
To make a single pom pom, I wound yarn around my four fingers about 110 times. I then took it off, and tied a string around the middle of the bundle and pulled it tight. Next I cut through all the loops and trimmed the yarn so it was uniform. These can be made many sizes and can be used for lots of fun things!
