I bought my Knitting Looms off eBay for about $4 and it came with 4 different size looms. Just follow the directions on the package (and my photos) and make sure when you tie the pom with yarn you do it nice and tight. Then once you take your pom off the loom make sure you fluff and trim it.
Choose your yarn of choice and a basic pattern for hanging them, grab a stick (you could spray paint the stick for an added details). Once you choose your pattern, thread a needle with the yarn and sew it through the center of the Poms to suit your desired pattern (tip: the yarn is thick enough you don't need to knot it and then the poms are also adjustable).
Find the perfect spot to hang your Pom Pom wall hanging where you can show it off to all your friends! And make sure you share it with us on instagram!
