Thank you Sarah, yes, I use different fragrance oils and some just won't work with these wicks. I test a lot. I think they also burn a bit hotter perhaps and this affects the scent throw, especially as they burn further down. As far as the wick clip, a smaller one would work better but I haven't found many options out there. The other wooden wicks clip is about the same size, I am not sure how to cut these and not leave sharp edges. I was trying to decide if putting the clip on the edge and adhering it off center might be an option but wanted to see if there were any other ideas out there. Overall, it's a pretty subtle difference, but I'm a type A wanna-be personality so I will never be satisfied 🙂
