First, I think It was great of you to go there for that reason.
I went to Jamaica on my honeymoon a few years ago and scrapbooked a 60 page album 12x12 on it. I use the typical jamacian colors as a theme. yellow, red, and green. The flag is green, white, and black. (You could go to Jamaica.com and look at the flag and stats on Jamaica to get ideas for the scrapbook, use your imagination and go wild. If you go to a scrapbook store they will have theme stickers for Jamaica. They even have jerk chicken stickers on it. You could also find stickers and die cuts of tools and tropical trees etc.
One of the main reasons we went to Jamaica was to site see Bob Marley, so my album is also themed around him. If you have any more questions that I might be able to help with just (pm) me. Most important have fun with it.
