Toughcookie- you have come to the right place...I have painted my bathroom five times (NOT A LIE), and the last time was sponged, and I love it. They also make a roller kit that does the trick, but I still think the hand technique (UBA- leave it alone he he) is the best. It couldn't be any easier. Pick your base colour. Then, depending on what you are looking for, and how large the area is, pick several sizes of sponge, and several pain colours, and after the base colour is totally dry, sponge on lightly. You will see how the coverage is, but, lighter is better. You can decide how much base you want showing, how big/bold the sponge shapes, etc. The best part? If you get too much other colour, just responge some base coat back on...
