I used a lovely chunky yarn made up of a mix of colours for a soft, mottled look to my pompom, and used a roll of sellotape as the template for my card circles (making my pompom quite large). You can of course use any colour yarn you like, and make your pompoms as large or small as you fancy (a selection of different sizes/colours would look pretty fab together).
Make sure not to trim the strands used for tying the pompom together - you'll need these to help you attach the pompom to the headband later.
Using six long strands of matching yarn and plaiting with two strands at a time, make a thick plait long enough to tie around your head easily. Knot the plait tightly at each end and trim any excess yarn.
Using the two strands hanging from your pompom, tie it onto the headband and try it on in front of a mirror so you can work out where you'd like the pompom to sit. When you've decided, use the pompom strands and a darning needle to sew the pompom securely in place, knotting any loose ends and trimming them neatly.
a fun pompom headband!
Sew your pompom onto a smaller plaited band to make an awesome ponytail bobble:
Or maybe wear your pompom as a necklace?
