Here's the bathroom for Sara's dollhouse. I haven't mounted the mirror over the sink yet. I wanted you to see the floor, which I created using PowerPoint.
I created this small, black and white tile pattern using PowerPoint software. It took a while, but it was less time-consuming than trying to create little tiles and place them piece by piece.
Once I got the pattern laid out the way I wanted, I printed it out on photo (glossy) paper to give it maximum gloss. After that, I sprayed it with several coats of glossy workable fixative to further give it a shine and to protect the ink from ultraviolet light.
The last part was the hardest - I had to piece together the floor, since the space was larger than the 7.5 x 10" image I got from the PowerPoint slide. If you study the picture very carefully, you might see where the two pieces connect.
