Don't worry about the title, we don't have a food prompt today!
Yes, It is Hot Cross Buns Day; but, we are concentrating on the cross part of the prompt. (If you feel led to make and/or photograph hot cross buns, please do so!)
In your travels today, be on the look-out for crosses or x's that you can photograph. You can get creative with word or letter tiles; or you can use a letterboard. You can also approach the prompt using the "x" or "cross" pattern as composition. Place your object where the x or cross intersects for a symmetrical look.
Places you can find crosses or x's: Church buildings, cemeteries, railroad crossings, animal crossings, etc.
