1) seeing as how these items go into checked luggage it is not an airline requirement to have them in the plastic bags rather then just making it easier and neater instead of having all the items just put into the tote bag loosely. 2) you can get Avery brand bags that come with the toppers from staples, but I think they are pretty small depending on how much stuff you want to put in them. Alot of brides just use generic ziplock bags from the dollar tree/dollarama, just look for ones that don't have anything on them, I've also seen bio hazard bags used which I think were picked up from either a hospital or doctors office. The choice is yours if you want to use cardstock of regular paper for the topper. I think using a lighter weight cardstock is best as it will hold up better than regular printer paper. 3) I'm definately doing a survival kit, not sure about an oh sh!t kit, it will depend on how much I can fit into the survival kit, if I have an over flow of items then ill do the 2 bags and just try to separate the contents accordingly to the theme. I do want to do a snack kit because I'm not staying at an all inclusive resort but this will be decided last minute depending on how much room we have left to pack. No templates yet for me as I haven't started designing them yet, but get creative!!! They really are simple if you have publisher or a similar program
