High school homecoming mums — once small flowers girls pinned on their dresses — are blooming into a Texas-size tradition of gargantuan proportions.Today’s mums seem to swallow up their wearers, as they’re festooned with miles of ribbons, and feature LED light displays and harnesses to keep them from falling flat. Guys don’t get left out of the fun, as they sport decked-out garters on their arms these days, too.High schoolers, we want to see your humongous mums and gargantuan garters! We’ll publish our favorites in Life & Arts, in print and online in a gallery, on a Sunday later this fall.Please send us your best photos of your mums and garters — from this year only, please — and tell us a little about them. The photo may be of just the mum or garter, or it may have people wearing their mums. How to submit: Email photos as high-resolution .jpg attachments to email@example.com with “Homecoming Mums” in the subject line. Please do not mail hard copies or use a photo-sharing service, such as Hightail. Size: They should be “actual size” if sent from smartphones or “print quality” at 200 dpi or better if scanned. Be sure to include: The name, address and phone number of the person submitting the photo, as well as the names of all the people in the photos (left to right) and high schools they attend. Also, explain the photo in a few sentences to give us some context about the mum or garter: Did you make it yourself? What are the features? Be sure to let us know when and where the photo was taken.If your photo is chosen, we may contact you for an interview to tell us more about it, and we may want to shoot more photos. Fine print: Please submit just one photo, so make it your best. No copyrighted or professionally shot pictures, please. By submitting photos, you agree to let the Star-Telegram publish your photos and names of people in them in the newspaper, on our website and on our social-media sites.
