Seven is theme for September Squares as it was seven years ago that squares was launched. September also happens to be the seventh month in the Roman calendar. To join in this fun challenge you could take a photograph at 7am, 7pm or anytime during the 7th hour, or the 7th month (which can be July or September!). Perhaps you have a favourite shot taken 7 months ago or even 7 years ago when we first began squaring. The number 7 might appear in your photograph or perhaps you want to go out and discover 7 objects like I have today. Whatever you decide to do though don’t forget your photograph must be square!
