How long will my fondant flowers last? Can I make them way in advance and then use them on a cake when I need them?

Welcome to CC

Yes, you can ake them in advance.
When they are dry and you are ready to store them, place them in a cardboard (food safe) box with a lid.
That way the air can still circulate around them....and they won't go soft.

If you are going to use them in a few weeks - (i have) laid them out on trays to air dry and placed a large food net over them.

hi...what is the longer time i can make the in advance...is 2 1/2 months too soon?

You can make them whenever you want. As long as you protect them from humidity, they won't soften, and as long as you protect them from sunlight and UV lighting, they won't fade. Proper storage is key. For safety's sake, add a packet of dessicant to the box in which you will store them (the little packages of silica beads you get in new purses and shoes), and make sure you've given them several days to air-dry.

thank you sherri!
