Great! I'm really excited for this and I can't wait to see what people come up with. I'll clarify a few things from my previous post though so everyone's on the same page.
- I think monthly is the best time frame to go for. As you say, people's lives can get busy and I don't want it to feel like a chore. (You can't rush genius!
) Normally, I think we should give the new theme on the 1st of each month (or close to that.) - I've changed my mind and I don't think enforcing a certain form is a good idea. Write whatever style of poem you want to or you think fits best for the sort of poem you want to write! Sometimes I think that maybe all of the different forms and the rules put people off, so I don't want to do that. If you do use a specific style of poem, do say what it is (it'll be a chance for everyone else to learn a little!).
Although I said we should usually start on the 1st of the month, I think I'll start this one today and give everyone (including myself!) a little bit of extra time this month. So, without further ado, here is the theme for August:
-The Seasons-
Inspired partially by the fact that Onion and I live on opposite sides of the world, and as such experience the different seasons at different times.
Now as I said, 'The Seasons' is the entirety of the theme here and so anything you write that relates to that is great! If, however, you are looking for a little bit more inspiration I've collected a few things from various sources to help get your writing brain whirring...
Spoiler
The Masque of Four Seasons by Walter Crane:

I mentioned music before, so of course there is an obvious choice here. Nearly everyone has heard
Spring before but perhaps you haven't heard the rest?
The Four Seasons by Antonio Vivaldi
If you live close to the equator, you don't really experience the four seasons like others do, but there are still seasonal differences. Here are side by side comparisons of a landscape in Zambia during the dry and rainy seasons respectively:

The image was taken from

And finally, after all this is a video game sheet music website, here is an extract of the Shadows of Valentia ending song (in English):
The seasons they turn,
Winter to spring.
Dulling the pain and
Erasing the sting.
The seasons turn,
Summer to fall.
Time's warm embrace
Begins to heal all.Also a bonus, more scientific image about the seasons:

I hope some of these help!
As I said before, I'm looking forward to this a lot. Also, I too am glad you've joined in E. Gadd! Hopefully you also would like to take part in this, but don't feel any pressure. I hope this might also convince some other people to have a go at writing... (We don't bite!)
To end, here is another haiku I just wrote now along the same lines as Onion's
V:
VII
Excited to be
Alive; Sharing, Exploring
A world neglected.
Edit: Of course don't let this get in the way of posting unrelated poetry. I'll certainly still be posting random haikus that I happen to come up with while walking to work.
