It's great fun! (Just keep the cats off the counter while you're mixing, lol - cat hair is my secret ingredient...) Keep us posted on how it goes and if you come up with a great recipe! It's not as hard as it sounds once you get going, and it's sooooooo much cheaper after the initial outlay. Plus you have a much greater control over what you're actually inhaling, lol...
Cheaper and tastes are my main reason. E.g. I can't seem to find a strawberry that's strong enough, that actually tastes like a strawberry. So I've decided to start making my own and see if that works better. I'll first do some standalone flavors before I start mixing them
