After days and days of practice I finally got the hang of making walls and floors. I even found a pattern for Green Eggs and Ham and just for fun I had to make that one.
I don't actually expect anyone to use it For this particular collection I made matching floors.
I have The Sims2 Ultimate Collection and these were made using Homecrafter, which by the way adjusts it wall and floor sizes. It's a bit of a challenge for me to see patterns on sizes 256X512 for the walls and 256X256 for the floors. All the walls and floors are $10.00, don't ask me why, I dunno.
