My CC list
MY SIMS 3 CUSTOM CONTENT LISTOne Billion Pixels - default replacement plates, clutter, male clothes
Anubis 360 - hair retextures: this is actually a gallery of all her clothes with filenames and links
Traelia - pose packs
The Grownups are Lying - posters, Ambitions tattoos, and the incredible painting replacement mod
Beatdoc - houses
Naver - clothes
In Anticipation - clothes and accessories, primarily maternity clothes
Sims 3 Updates - lists the most recent cc with pictures and links, can filter by category. A great resource.
Ritsukacom - objects, clutter, beautiful cc heavy lots, heavily influenced by Asian culture
Sweet Ambrosia - clutter, no longer creating
Lotus' Journal - sims, hair retextures
Papercat - skins, makeup
MODS
Anach's Sim 3 Mods - little tweaks for TS3, I use most of these
Nraas - core mods, my favorites are story progression and expanded tattoo, you need the master controller for any of these to work I believe. I don't think I would play ts3 without these mods.
RULES
Infinite Improbability Legacy Challenge - the legacy challenge I try my best to follow.
Lazarus Challenge - apocalypse challenge I tried and failed, but really enjoyed and will eventually go back to
**these are the sites I get most of my custom content from for anyone who is interested. :)
***I will add to this as I find more sites. MTS and GoS go without saying. Please check them out now if you haven't already.
