Making Sims 3 paintings

Recently, I discovered how easy it is to make paintings with multiple images for the Sims 3 and I have gone crazy with it. I have made two sets of anime posters, a set of video game and movie propaganda posters, and two sets of yaoi paintings already. Me thinks I have a problem.

Making Custom Content Makes me want to scream sometimes

I am a beginner creator, but sometimes stuff that should be easy, decides to fuck itself up and make me work harder than need be.
I made a set of superhero themed baseball shirts and they went all fine until you go into CAS and try to change the pants while your sim is wearing the shirt. It then goes all one-colored and won't recolor in advanced CAS at all. I am sure it is an easy fix, but I am just slightly annoyed so fixing it is going to have to wait.

Soooo..... Pets!

Sims 3 Pets is out and I absolutely love that we get horses and the wider range of minor animals like snakes.

Meshing Issue

So I decided to start trying to make hair for the Sims 3. it was fairly easy enough. However, I am having the hardest time getting the polycount low enough for the lod3 file. Milkshape just isn't doing it. Everything else went pretty smooth. I looked up solutions and sorta found one, so now I am downloading the trial version of 3dsMax to see if that will work. Lets hope, so I can move on.
