3 Dimensional Art

I have been reading a few different blogs that show their altered pages.  Most have some interesing three dimentional items on their pages. Plus reading how some people put together found objects.  I have boxes full of found objects. Most are rocks, shells and other items discarded in nature.  At least I find them while out observing nature. I can't resist bringing some things home.

I have been inspired to try one of these altered pages.  Or in this case it didn't end up as a page. I made a small collage of found items. 

Obviously not all items are found but nature was in my mind when I put them together.  The Frog is of course a Chinese (?) knot.  It isn't a real frog but it suits my sense of order. The piece of coral and a crab claw are real.

I put them in this black frame.  My only disappointment in it was that the blue paper bled through the red paper with the chinese writing.  I was going to send this to a friend but with the error of the bleeding I can't do that. I will keep it for myself as a lesson learned.  I am afraid that the crab claw is too delicate to take off the piece so I could place another piece of the red paper over the original. 

If any of you do this type of art would you tell me what kind of glue to use that would possibly not be so wet as to make the paper bleed?
