Definitely read Dannyv45's blogs! I still haven't gotten to read everything but everything I've read had been very helpful. My suggestion would simply be that, if you are thinking about any other than single flavor recipes,, find the recipes and make a list of the flavors you will need. I didn't do that and, as I was just explaining in another thread, I have 50+ flavors cuz I thought they sounded good (in my head) but once I find a recipe, I am usually missing a flavor or 2 that is required to complete it....lol!!!
I haven't gone to glass storage bottles yet but I intend to do so very soon. Also, I'm considering trying testers without nicotine cuz that's the stuff that really costs the most.
