This is one of the designs that I came up with today ...
The coffee cup watermarks were made in Photoshop but I researched how to do one in MDS with SU stamps and found a way to actually save the watermark so it can be re-used over and over!!

Here's another watermark made with the digital 'stamps' from Birds of a Feather Collection - cage and thin bird silhouette (25% off this collection, along with many more downloads, until May 30th. See my on-line store for more details).
That's another thing off my very long list ...
