My mind just travels in all directions when it comes to seasons.
You could do:
January----something to do with New Year's
February---groundhogs
March----windy runner
April----showers
May----flowers
June---??? don' know what goes on in June except weddings
July---Independence Day
Aug---lizard on a hot rock (my birthday is in Aug. & I always say it the Lizard on a Hot Rock month because all the calendars seem to put that on their pictures because Aug. is always so hot...heheheh
Sept.----Fall theme
Oct----Halloween (even though I'm not much of a Halloween fan)
Nov---Thanksgiving
Dec---Christmas
Most of these are not very original but may start your imagination going.
