I often send packets of my own processed macnuts, a favorite among my friends. And home dried tropical fruits : rambutan, pineapple, banana, jackfruit. Commonly I'll include jars of my own honey or homemade fruit syrups......lilokoi, mango, guava, etc.
I like the pretty-up the jars, considering that they are gifts. I especially do this around the winter holidays. It is so easy to do and cost just pennies, sometimes actually zero! Often I am given unwanted or damaged aloha shirts. Sometimes I'll buy one real cheap that catches my eye at a yard sale or at the thrift store. Once I bought for just pennies a piece of cloth left over someone else's craft project. They make a nice decoration with a bit of Hawaiian flavor.
