Yet another question about templates :)

Okay, I completely understand how to use templates. and I understand the concept of how to make them. What I'm wondering is (especially in Photoshop 7) what tool do you use to draw the template with? Paintbrush, pencil tool, what? Especially where little bitty hearta and stars and such are concerned. How do you get these little things the same size, etc and not to where they look like a little kid with a shaky hand drew them?

Also, if you use the paintbrush tool, which brush do you use to get nice crisp clean lines. Not just straight lines, but all of them?
