Ibex, I love to see your work too!
There are several blocks called mosaic, and they are usually numbered because there are so many. The one I did was Mosaic #11. That one, and Mosaic #12 are both found in the first Around the Block book by Judy Hopkins. In the second book, Around the Block Again, you find mosaic, mosaic #3, mosaic #10, #19, #21 and 22. Mosaic #8 is found in Once More Around the Block. There is nothing special about them, they just look like basic pieced blocks.
There are 4 more mosaic blocks on Quilter's Cache, as well as a mosaic star and a mosaic rose.
