I miss those days! My favorite I did for a class, I did with 2 friends as a group. I am fortunate to have a seamstress for a grandma so she made the costumes. My mare was the bride, my friends gelding was the groom & another friend's mini was the ring bearer complete with gilded & pearl horse shoes. Jana HATED her garter belt, she walked like she had stringhalt lol!
At our county fair this year there was a boy who must have spent an intense amt of time with his parents making it. They turned his pony into a putting green, big circle on top of him - I assume heavy cardboard and covered in indoor/outdoor carpet w/the cup & pin flag. The boy dressed in old style golfer gear and carried clubs. The pony had a sign on his butt that said "Don't let them fool you, I maintain the grass."
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
