Adventures in grouting tile!

This was my first experience cementing and grouting tile and I now have a great appreciation for those who take on entire bathrooms and countertops! Here are the results of grouting my custom ceramic tiles from Cafepress into three 9 x 13 black wooden trays and two smaller bamboo dishes:

With two more trays on hand, I'm thinking of making a mosaic tray where the six tiles create a single image. I'm thinking the green sedum image will work very well for this project where the original image is cropped to new dimensions for the tray.
