Thought I'd add my 2 hearts as well. I made them both into phone charms too. The first is the heart pattern available on the site and the second orange heart is the same pattern but using the same size beads (instead of 2 different sizes).

Jax, I think the beads you're using are called size 8/0 and I use them too (you say 'eight-aught'). They actually measure 2.5mm across. The standard seed bead sizes are 6/0, 8/0, 9/0, 10/0, 11/0, 13/0, 14/0 and 15/0 (in order of decreasing size).

Thanks for your kind comments

Oooh, I found a guide to seed bead sizes on the internet (boy was it hard to find though, you would think there would be better tutorial sites out there!), and it said that the ranges of seed bead size are size 6 (largest) to size 15 (smallest), and the size 6 seed beads are also referred to as E-beads.

The size 6 seed beads fit 6 beads per inch, and the size 15 fit 15 beads per inch, hence the naming system.

The size 6 seed beads measure about 4mm, the size 8 seed beads measure 3mm, the size 11 seed beads measure 2.2mm and the size 15 seed beads measure 1.5 mm (according to that website).

So as Laura pointed out, people use the nomenclature of "6/0", "11/0", etc to refer to the sizes. I don't know what the "/0" is for. LOL! Do you know Laura?
