Take photos of things that look like each letter (and/or number) but aren't - accidental wet marks, branches, placement of rocks, the way a plant stem curls, the shape of a cloud, the way something hangs - and so forth.

• Make a series, perhaps.
• Find enough to create your first name or that of a loved one and gift it to them.
• Use them to make a word that you can use as the inspiration for something else - the cover of a book, the centre of a collage, the background for other things, etc.
