I was repositioning Flame's eyes today (also the stem type) and accidentally made a discovery. Those eyes are two piece and the stems can be removed leaving just a half round eye. With that option available I switched from the default eyes she was wearing to these brown ones which I liked better. I also added a set of eyelashes while I was at it.
I still went ahead and ordered her some new eyes today, catching the last day of a 40% off sale at Masterpiece Eyes. They will be a similar colour but the iris will be one size smaller allowing for more flexibility in eye position and expression.
Tingle's top, leggings, and shoes were all a gift from Ban of Ban's Boutique.
