I'm doing wedding cake cookies for my niece's wedding this coming Saturday. I'd like to do MMF since I have some cool texture plates that came with the cutter, but I'm afraid the MMF will melt (outside wedding/reception) and the texture will fade, plus everything will be sticky.

Does anyone know if that will happen?

Thanks so much!

I just did baby shower cookies with MMF they were individually bagged and left outside in a basket for the guests and they were fine. It was this past Saturday (June 6) and the temperature in CT was 78 and very sunny.
The hostess did have a canopy over the deck for shade but the cookies did not melt or fade they were done in pastel baby colors.

Awesome! Thanks for your input.

I'm wanting to do white MMF with pool blue accents (probably in RI). It's supposed to be 79 (and I think they're keeping them under a pavilion), but the humidity will be high, so I'm sure that will factor in too.

Just thought I'd post that I did 60 of these with MMF (stuck on with corn syrup) that also had mmf flowers attached. They weren't in a sunny location, but it was 85 and terribly humid.

No problems with melting whatsoever. The cookies didn't loose the impression I did on the mmf either.

Yay!
