I'm heading to Germany next week and I really wanted to be organized this time around. I do struggle with travel organization. SD cards are a problem because they're so small and they tend to fall down into the cracks of bags. And let's be honest if you're shooting raw photos a 32 GB SD card can fill up pretty darn fast so you need a couple of them for a long trip. I don't plan on bringing a laptop so my only method of holding these photos will be an abundance of SD cards.
I found a great SD card holder that I highly recommen. It's from a company called Link Depot. It's small, it holds a ton of cards, it zips up and it's unbelievably cheap. Ordered in on Amazon and it was here the next day.
