Chelle- thanks for explaining that!! That's what I get for ducking out for a few months. Miss somethign that sounds amazing!!
as for the DIY supplies, you'll need a way to meassure what you're mixing pippettes or syringes, and some form of graduated cylendar, you'll need bottles(5 ml are great for personal use, I don't go bigger than 20ml becuase that's what I use when i have found something I really like...

3ml if you're going to do samples), and santiation supplies. Depending on the mg in the nic juice you buy, you may need PPE (personal protective equipment). You will also need flavoring. Everyone has their own preferences. And I saw UTRose say not to get lorans, but when you're just starting out, lorans is cheap and you don't feel bad for wasting it while you're learning.... lol. at least I didnt!!
so:
bottles
flavoring
PPE
measuring tools
Extras:
a small funnel (has made a world of difference for me)
syringe tubes without needles (great for helping to mix!! slurp it up spit it out and repeat)
tackle box to hold everything
that's just kind of the basics. You'll potentially get some freebie items you'll love, and you may order stuff you find out later you hate. it's all about preference.
