Hello! I just wanted to point out to you an awesome tutorial on making your own watermark! You can find it on Rita's fabulous blog Coffee Shop.
I just had a quick play, and made this watermark:
The main font is called 'The Blue Cabin' and is a fantastic free font from Kevin and Amanda's Free Scrapbooking Fonts. The ant is from the DB Animal Occasion font from scrapNfonts.
Rita's tutorial goes on to show you how you can load your watermark up into Photoshop as a brush, so it is available to be used at any size, colour, and opacity on all your edited photos. Groovy.
In my watermark above, I decreased the opacity of the ant layer slightly before I merged the visible layers, so that he will appear lighter than the text when I place him onto my photos..e.g:
Have fun watermarking kiddos!
