Modge Podge is the old decoupage stuff and it works great with water color
backgrounds. That is exactly how it was used with the seashells. Shells were
outlined in permanent sharpie, filled with color and then modgepodged. Water
color was the last step.
I also tried this weeke something else that was mentioned on the list. My
fourth graders are working on an extinct animal composition and they looked
through old geographics and found a picture of something that related to their
animal or its habitat. They coated the picture with maybe 10 -12 coats of
modge podge, allowing some drying time between coats. When it is thoroughly
dried, they peel the clear coat off the page and the picture stays on the back
of the modge podge! It is SO cool and these kids think it is magic! They
will incorpoate this picture into their collage -- just haven't figured out
the best way yet.
