I am new to cookie decorating (usually do cakes) so I have some simple questions.

I just finished decorating and bagging Cream Cheese Sugar Cookies with RI. I baked them and then froze them. I took them out to thaw Friday morning and decorted the base that afternoon. I let them dry on cookie sheets and then finished decorating them on Saturday. I let them finish drying on cookie sheets and have no bagged them (today, Sunday). My question is this: The shower is on Wed evening...should I refreeze them or will they be fresh enough for Wed or a few days longer for people to eat them?

Mine stay fresh for a week, so with that said I would not re-freeze them. When the RI is completely dry, I do wrap immediately to keep them fresh

I would definitely bag them as soon as the icing is dry to keep them fresh longer. No, I wouldn't refreeze.

If you have a cello bag, heat seal the ends. I do this and then either tag them or tie a ribbon on.

Where do you get cello bags? I just put the cookies in clear treat bags with a silver twist tie.

I get mine at the local cake supply store, but unfortunately they don't ship. You might try U.S. Boxes to see if they have any if you don't have a cake shop or Google it. Cello is so much better than the plastic (like you see at Michael's). SO much better.
