Paper Bead Question :)

[sin-da-rella.livejournal.com]

Thanks for all of the advice about making paper beads! Now that I have started making beads, I have a few questions....
I have quickly realized that triangles, no matter what width, make oval-ish beads. And if I were to cut the paper into strips, I could make square-ish beads. I would like to make round-ish beads and the bf thinks that if I use a diamond shape (a skinny one), that I could make them round, but I am skeptical. Is he right? :)
Also, what the heck other shapes can I cut the paper into to make beads?
Thanks!
