My brother is having a wedding Hawaiin themed. I want to make soneting, but what?!

Instead of a common mailbox or bird cage or money bag for envelope gifts you could make a mini straw hut for their envelopes, or you could also make light up palm trees for their entrance way by buying about 5" diameter see through green tubing however tall the entrance way is and making the leaes out of cellophane and wire to make the outline and then fill the plastic tube with christmas lights so they light up trust me it will make a cool accent to their theme i use to do party planning and have done this before
