I'm throwing a shower in August for a friend who is getting married a couple weeks before us. She's very outdoorsy; a great climber, kayaker, hiker, etc.
So I've been toying with the idea of a shower that is 2 parts elegant tea party with 1 part camp flair:
Flowers - "Wildflowers" in tomato cans or something else low key.
Favors - A red carabiner would be a handy party favor. She's marrying into a Chinese family, so I want to incorporate the lucky red color as an accent.
Food - Lots of delicious tea sandwiches. Served with little cups of homemade tomato soup.
Activity - Pub quiz! Related to a traditional shower game, but more fun. I could customize the questions to be about camping, etc.
Gifts - Encourage people to bring "gear" gifts from REI.
Dessert - A gourmet version of dirt cake could be fun. I could make chocolate ice cream from scratch.
