I dust them before freezing. In fact, I do mostly dry dusting and you need to do it before the fondant dries. The drier the fondant, the harder it is to get the dust to stick, JMHO. The shine will not go away. I have frozen many dusted cookies. HTH
You are welcome. I use a nice soft natural bristle minimop brush to dust with. Find it goes on more evenly.
Glad it worked for you, that's a lot of cookies 
Hi linedancer -
Whoops - I don't have enough room in the freezer - I'm guessing I should put the rest of my fondant cutouts (no cookie attached) in an airtight container, right?
I hope I'm doing this right: I'm cutting out, dusting fondant and then will bake in 2 weeks and adding fondant while cookies are hot. The fondant should still be fine? I have never put fondant on cookies when they got this hard before. I feel like I've never baked before!
I think I'm starting to panic - wedding in 4 weeks!! Yikes.
Thanks.
Don't want to upset your apple cart, but I do not know how the pearlized fondant will look, if you put it on hot cookies. You might want to do a test, to see if that works. No harm, if it doesn't, just a little more time to apply the fondant with some thinned karo to the cooled cookies.
Do you have any refrigerator space? I would layer the fondant between sheets of plastic wrap, put in a container, and then in the fridge, if you have room.
If you could beg, borrow, or steal some freezer space, you can bake the cookies, apply the fondant, and even bag them, if you are going to, then freeze. That way you could do a couple of batches a week, and not have to bake them all at the last minute.
If you freeze the completed cookie, they are as good as the day you put them in there. I have a 300 cc wedding, a 100 cookie party and a 100 cookie demo the first two weeks in October. I am going to start baking right after labor day and into the freezer everything will go...
Thank you linedancer!! 
You have answered ALL my questions and more. I will follow your lead.
After the wedding I will post pictures (if I know how). They will be 200+ cookie cake favors (3 cookies stacked with gumpaste flowers on top).
I'm pooped already!
Again, thank you, thank you.

You are welcome, will be looking for your pics.
linedancer- how do you package the cookies that you freeze. I asked this question once before and people recommended not freezing decorated cookies? what is they best way to keep them fresh and not freezer burned? Do you freeze RI ones too or just fondant?thanks!
I do only fondant cookies, so I can't tell you about ri. I do know you can use ri decorations on fondant and that is ok to freeze.
If I am going to bag the cookies, I do that, using an impulse sealer. Then I layer them in a plastic container. I use the sheet cake carriers you can get at Walmart for about $6. If I am not going to bag the cookies, I layer them between wax paper, then into the plastic container.
If you can't get them into the freezer with the lid on, I cover them with aluminum foil. I take them out the night before I need them, leave them on the counter in the container. The exception to that is if they have eis on them, then I lay them out individually, so they don't smear. I have kept them up to 4 weeks this way with no problems. HTH
ok I am confused. Sorry ladies. I am making cookies for a wedding as well. So I can bake the cookie, attach the fondant, and freeze them in advance? Wow, nice. Won't the fondant get freezer marks from stacking? Also, how do you attach the fondant to the cookie?
Tracya Yes, you can bake the cookies, decorate, and freeze them. This is with rolled fondant for icing. You can also use ri accents on the fondant. I use thinned karo syrup to attach the fondant. Others put the fondant on while the cookie is hot from the oven, still others use butter cream or jam/preserves to adhere the fondant.
The cookies look as good when you take them out as when you put them in. Earlier in the thread I explained how I packaged them for the freezer.

Wow, what a great job, they are beautiful You are welcome.
