I didn't make it to very many panels, but I really enjoyed the ones I did get to!
The Wig Styling panel was very useful and information, though maybe next year it could be separated into a beginning and an advanced panel, since I felt much of it got taken up with basic information, which I personally didn't need as much of. I would have liked more time spent on techniques for shaping different wigs, and maybe even how to incorporate accessories with wigs. Overall though, a very good panel!
The Advanced Sewing and Patterning panel was also very good. I missed the beginning, but got a lot of helpful information out of the later part. I wasn't bugged by it being a group panel, I thought it worked out well and offered more points of view. I already feel the itch to try out some of the techniques that were touched on, and I need Pattern Master and a ruffle foot STAT.
My request next year would be to try not to schedule costuming panels on top of each other. I wanted to go to the weapons and accessories panel and the wig styling panel, but had to choose between them.
Also, I didn't make it to them myself, but my friends reported very negatively about a lot of the writing panels. It sounds like some people running them were giving out blatantly wrong information, or presenting style choices as hard facts.
Also, I desperately wanted to make it to the LGBTQ panel, but since it was in the middle of the cosplay contest, I wasn't able to. I know it's very hard to try and schedule everything around the big events, but maybe panels could happen multiple days, so people have more chance to get to them? Anyway, that may be impossible, and I know you guys do what you can!
Overall I was very happy with the variety of panels this year. I didn't even make it to that many, but just flipping through the con handbook and reading about all of them made me very excited. It seemed there was a lot to do this year, even if it all wasn't my thing. Kudos!
