I have been organising the "Night of Churches" event in Riga St. Mary Magdalene church for 3 years now. And every year I design posters and other prints. In 2014 I designed the steeple with flowers and the color scheem, and have kept it until now, and will propably keep it even in years to come. 

 

2014 we only printed small A4 posters. Last year and this year we had several sizes smallest being A3.

Small pirnted programms for handing out to people.

Folded size is A6. I find A6 to be a very practical size, and with a fold you can put a lot of text on it. It is also easy to print, you can fit two of these on an A4 sheet. 

Comments and feedback are appreciated!
