My hobby too. Your only limited to your imagination, as far as flavors to make. I stopped buying store or on-line e-liquids over 6 months ago. Not so much to save money - although that was one benefit. I just couldn't find a juice I really, really liked. I found some I liked for about half the bottle, then, I got to where I couldn't really taste it any more. Or I'd buy a juice based on description and when I got it, it didn't really taste like what I expected it to taste like. I like what I like ! So I just make my own. I take one Saturday a month, and make about 10 flavors. Sometimes I keep same flavor going in one or two of the bottles for 2 or more months... just make a new batch. At any given time I have 4,5,8 or so bottles in steep, and 4 or 6 or so bottles I'm vaping from. I like to vary flavors through out the day. It keeps the vapors tongue at bay. And I can use what ever mg/ml nic I want. Usually 3, but some bottles contain 4.
