Alphabetter
Using the alphabet as your guide, you could:
Collage:
Create a collage of things you like or favourites using images you take yourself or ones cut from print media.
Pen:
Try a different form of writing that starts with each letter of the alphabet - acrostic, boustrophedon, calligraphy, documenting, echo poems, etc.
Memories:
Document your memories - first art show, blueberry picking, learning to crochet, etc.
Adulting:
You could also use the letters of the alphabet to plan something you need to do that starts with each of them. Such as: accounting, baking, cleaning, doctor, etc.
Write:
For each letter of the alphabet, write about a topic that starts with that letter.
Initials:
Do something, and detail it, that starts with each of your initials.
