ok, so i took my gumpaste and fondant out of their packages and put them in zip lock bags for storage. now I can't tell which is which. anybody out there that can tell me how to determine????

Hahahaha! Take out a little bit of each and roll them out. The gumpaste will roll thinner and won't tear as easily, it will also stretch more.

Gumpaste should stretch a bit like warm mozerella cheese.

taste them.

and I did the same thing. luckily, it was small balls of each, so I just gave them to the kids to make fiquerines out of. LOL

Some gumpastes start off a little off white in color until they are dried.

As the others said textures are different. Fondant will be softer, where as the gumpaste will have a thicker feel.

Taste them.

Lay a little piece of each out and see how the dry. Ive done that before too. I save the small balls of color fondant and gumpaste and then I can't remember what it was. I try to remember to mark the baggy with a f or g. lol

Mix them together and put them in a bag labeled Fondant/Gumpaste Mix ... Done!

usually gumpaste is harder, fondant softer. fondant also will tend not to hold minute detail well. gumpaste can be rolled uber thin (helpful to make all those flowers!!) HTH
