I have no pictures.....but have seen the supports wound with fabric and flower garlands.....and have seen green silk foliage covering the struts wound with little clear electric lights.
My experience with battery powered lanterns is they don't last very long at all....better string wire.

Here is a picture of a tent that we did with the paper lanterns. Also we put twinkle lights around the inside of the tent. You could also drape the insides with school color material. Our Walmart has a lot of material $1.00 a yard. When my son graduated I took pictures of him and glued them to construction paper (school colors)that had been folded in half and placed them all on the tables. Standing up. I had seen where people do scrap books, which are nice, but I noticed a lot of people don't take the time to look at them. This way they where out for everyone to view.
Good Luck
