Disclaimer: I haven't bought from most of these shops. The reality is that fandom candles are usually expensive. Add in shipping and it's just like, not smart for me to buy them. Which I understand! People are putting a lot of time and effort into this and SHIPPING IS AN EXPENSIVE THING. I'm basically just showing you pretty candles I WOULD buy and probably only would buy as gifts for birthdays and stuff like that because I'm irresponsible enough at Target, I don't need to be buying myself 10 candles from Etsy, too. (Also, all photos besides the one above are from the shops themselves, not me!)
Obviously I'm going to start with Hafsah's shop, IceyDesigns, just in case you haven't heard of it. Her shop has plenty of stuff that's perfect for book lovers, really - journals, including a Six of Crows one, cute pins, pencils. But for candles, there's one for Caraval, one for Windwitch, one for An Ember in the Ashes, and more! They all look BEAUTIFUL, and the candle for The Star Touched Queen sounds particularly awesome. Candles are 8oz jars for $18 (without shipping - ships from USA).
