By the time I'd finished it and proudly shown it to the original creator I was in the mood for making more, but seeing as together we had ruined the pom-pom circles I rummaged in my knitting stash for an as yet unused pom-pom maker I'd been wanting to trial. I shouldn't have bothered! Just look at the sorry excuse for a pom-pom - it's weedy and not at all 'succulent' and plumpfy as a real pom-pom ought to be!
The main problem was that it was very difficult to actually keep the yarn on the darn thing without it all falling off. And the diagram for starting and finishing was so unclear, that although I followed them 'correctly' the whole thing unravelled before I could tie the knot! My advice is to bin them as I did - the one here was only kept for the purpose of the photo then joined his companions medium and large in the wheelie bin.
Old-fashioned cardboard circles are far superior and work every time :)
