CarolJude, she downloaded the sims and changed their custom content.... which takes about 3 minutes. Custom skintones change the look of noses and make sims look more realistic, and we all know how easy it is to change a sim's hair. In this case she changed Sookie's hair, skin, eyes, brows, and makeup, and -maybe- tweaked the face sculpt a teensy bit. It's honestly hard to tell since both pics are taken from the side and the second one is very distorted. But she most certainly started with my sim as a base. She's even still wearing the shirt I made for her.
Bill is completely my face sculpt, no question. He's wearing the hair, hair mesh, and sideburns that I made specifically for him. He's wearing the faint (and admittedly not great) upper-lip and chin dimple that I made for him, and is -only- uploaded with my Bill sim. He's wearing the same exact Maxis stubble and custom eyebrows as my sim. He's even wearing the outfit I packaged him in. She simply downloaded him, changed his skin and eyes, and removed his faint character lines. That's all.
In no way, shape, or form, does that count as making them herself.
