I print my calendars on glossy photo paper, A4 size and horizontally, I can make the dates start on sunday or monday depending which side of the Atlantic you are on  ;)  just let me know.
I have an 'Ancient Ireland' calendar with stone circles, standing stones, ruins on it, or a Landscape one, or a 'Frog flower'  one, some being wildflowers I saw while we were out, and some being in my garden, and some being  manipulated to give them a different look.
My 'landscape collection' is growing all the time there are currently about 30 photos I use regularly that I know print out well, you can trust me to choose or custom design your own by selecting any titles from my DA site and I will create it for you.

All calendars are 8 Euros and that includes shipping anywhere.

Of course everything you can see here is available as notecard or print also.

Landscape Calendar

Below are the main selection of photos I use for my calendars

Frog's Flowers Calendar

Here is a sample page  :)    ...January, I tried to make the flower colour match the month... or the mood of the month, but as always my designs may vary slightly, either because you ask or because I get bored printing the same thing  ;)

Ancient Ireland

These are the 12 photos I use for this calendar, slight variations my occur as I change the borders sometimes  (and sometimes the photos too,)   but this is basically it.
