It is hard not to bring too much but a lot of extra work for yourself if you do. Try to pick a certain group of pictures you want to scrap. Organize the embellishments you will use, tools, paper, embellies and don't forget lots of running tape. Keep in mind most crops have vendors so if you need something you did forget, you can always buy it. Have fun, you should get a lot done, but not as much as you think you will so try to not bring everything.
