I selected 'Template' and chose to dim the image to 60%. I then created a new layer to enable me to draw over the original image. I used the pen tool to create my outlines and the end resut was quite effective. I am glad I have finally dipped my toe into Illustrator!
This is how it looks so far. I will put a door into the door space at the back of the room (this will be the door she never opens). I have now got to decide on the colour scheme. I wanted a grungy texture on the walls and searched for some free textures. I then had the problem of knowing how to apply these to my scene. I am so new to Illustrator, so I feel very clumsy around the application! I used the help files and online help and some trial and error of my own to apply the texture to the swatches. I was doing what it said in the help files, but it would not work, then I realised that as the texture was a bitmap it would probably need to be rasterized in order for me to be able to copy it to swatches and thankfully this worked!
Then, as I am so used to using Photoshop - I could not understand how to apply the texture to the scene... I could see the 'live paint' tool, but could not get it to work - I just wanted to use the paint bucket and place the colour into areas within the scene! I knew I had to get out of Photoshop mode and I pondered a while and decided to group all the paths together to see if this worked and fortunately it did! I could then use the 'live paint' tool to apply the texture. This is probably all very obvious to Illustrator users, but a bit alien to me at the moment. I applied the textures, but although it looks ok, it is not the look I want.
The look I really want is to be able to have some transparency on the texture and place a colour over it.. so back to the drawing board and search online to find a way to do this :)
