I've been mixing since I first started vaping.. Seeing as I was using clearos at first, I bought flavors that would mix well together. Moved on to dripping and kept buying flavors that would go together, as I like to change flavors throughout the day. Wasn't long before I was having my local shop mix up custom blends, but that was expensive and a few times disappointing. Now I DIY due to cost and my inner chef thinking I can make better flavors for my tastes. I've only been at it for a little over a week now, but everything I've made so far has been great, to me at least. I've found that vanilla, custard, and bav cream all complement almost anything (and taste great together).
