Any ideas for a fall/autumn theme wedding?

Just yesterday I decided to bump my wedding for 2 months from now. I didn’t have much else booked, so I’m kinda starting from scratch. I have the ceremony and reception place booked and set to go I just need to change the dates. I just need help with coming up with ideas especially under short notice. I already have planned for the theme “Fallen in Love”. I want carved pumpkins with hearts carved into them and a candle burning inside. Each of my bridsemaids will have a different color dress than the other to represent leaves. Sunflowers will be at each isle of chairs at the reception. Is there a way to sneak in a lil bit of light blue (i have light blue sparkles on my dress) and have it go with the rest of the theme? I already have my dress, so that’s the only problem. Any websites that could help plan a wedding in two months? And I’m going for a fun theme and nothing too formal.
