LaBlanche - Foam Mounted Silicone Stamp - Nest with Eggs

It looks good, but the stamped image--not so much!

I bought this stamp to add interest to some of the Mother's Day cards I am making. I admit I have not used a foam mounted silicone stamp before, but after trying markers, ink pads and trying to add details using water color pencils, I was not happy with the results. Most of the problem, I think, is that the stamp is difficult to hold and the nest portion of the stamp is nearly flat with no raised details. This makes for a squishy mess on the paper. If there are any suggestions on how to make better use of this stamp, I hope someone will post a comment.
