The Almanack is tiny.
It measures 7.5 x 10.5 cm ( 3″ x 4″).
And there are only 8 pages which includes the contents on the cover.
All this is to say, keep your poems for the Almanack short.
A maximum length of 18 lines (including lines breaks) and a maximum width per line of 45 characters (including spaces).
Happy creating!
