EDITED TO ADD: Thanks for asking how I did my mosaics. I am so flattered. My tutorial for making mosaics on Photoscape can be found by clicking on the tutorial near the bottom of my sidebar. Photoscape cannot be used on a MAC computer. If the tutorial is not clear, please email me, and I will try to help.
For links to mosaics, please visit Mary at Little Red House. Thanks for coming to visit me. laurie
