Hello Louisa, I've had my shop 3 years and I still wonder on a daily basis was I INSANE haha!!!! I'm going in later to catch up on admin . We are lucky with our windows as we are on the shady side of the street and the windows are also recessed from the pavement. We don't do special window displays, they are set out as part of the main interior shop displays with plants and pots etc. We used to have a workbench in one window, that caught people's eye and it saves the headache of thinking about what to put in it each week. On the losing customer front, yes you will lose some, but you will also gain some too .
