Hi! I don't know if I am allowed to publicize this, but if you join Yahoo Spoolknitter (of which I am the current moderator) you will find heaps of patterns both by members and also in links. We have many talented designers in the group and we also have competitions. We have members who also collect the spool knitters - old, new, and handmade.
You can also get ideas from the pages of the Flickr Spool Knitter group which I also manage. Maybe we will see you there! .... cheers, Maz
