This stamp set is great for masculine cards! Here is a card that I recently made:
I used the following to make the card:
Kuretake Gansai Tambi Watercolors #44 Light Brown, #47 Dark Brown #62 Cobalt Blue
Stampin' Up Wetlands Stamp Set
Memento Rich Cocoa, Cottage Ivy
Stampendous Detailed White Embossing Power
Using the watercolors, I created the background. The birds were then stamped using the Rich Cocoa Ink. The reeds were stamped with Cottage Ivy. The entire piece was then cut down, matted and added to the card base. The sentiment was stamped with Versamark, the embossing powder was added and heat set to complete the card.
