A project that takes about 10 minutes is a Crochet Key Card Holder that can attach to a lanyard or whatever. For cruise ships, the key card is your most important identification. For personal and crochet cruises I attend, I wear lanyard so I can keep an eye on my key card, so I don’t forget it in the cabin so easily.

I recommend Lily Sugarn Cream yarn as an option as cotton is strong and won’t fray quickly with continuous use.
