1. 1 of my sims grew up to be hella ugly. I want to replace it with a sim that i made in body shop. I'm pretty sure there is a way to do it with Simpe. I just haven't found it yet.

2. I want to create my own new custom posters and paintings because I dont really like the size of the default ones. I've been searching for a tutorial for weeks, but I've been unsuccessful in locating 1.

I'd really appreciate it if someone could help me out by showing me how to do these things or atleast point me in the right direction in terms of finding a tutorial.

Um why dont you try "Live chat" on the top of the page
because the modderaters are so sweet and kind... I had to get help because i wanted to upload sims on this site! So give it a try and give me a shout!

1. http://www.modthesims2.com/showthread.php?t=74939 - That is a link to Grapholina's tutorial. You must follow the same steps in the tutorial but change the preson you are replacing instead of Gina Seavey.
