Thanks so much for this! I have been searching for new CC sites, and I found a ton with this
Thank you so much for all the links. I have been looking for custom content and recommended sites are so much better.
I love this list, it’s been really helpful! Although some of the links doesn’t work anymore, so you should probably check that up. ^_^ (I don’t really remember which links it was…)
Anyway I think you should add subaxi and lemonleaf to the list! http://lessims3desubaxi.blogspot.com/ and http://blog.sina.com.cn/lemonleafs
I love their stuff!
Thanks for letting me know. I updated the list
Thank you so much for this list! You may also want to add, in addition if you need to sign up, if they’re paysites or not, like Peggy and TSR are.
Thanks for the idea! I will definitely do that on my next update.

Hi, there’s a hair blog;

That I think is really good, he sometimes makes his own hair, but it’s mainly re textures and conversions, personally I think they are amazing.
