Entry ways
Gallery:
If you find a cool leaf (or something else) while out and about, fix it into your journal and write a little exhibit label for it like you were in a gallery.
Write on:
Write your notes and entries on all the bits of paper and card you've hung on to - old cards, tags, ledger paper, sheet music, maps, envelopes, etc. and glue those into your journal. Use your junk not just as decoration, but as a potential canvas for your writing.
Circular:
Your writing doesn't need to be straight and neat. You can write in circles, on angles, change the size as you go, around images, using cursive, using printing.
Sew:
Sew some words into a journal entry, even sewing along already written bits of text to add a little texture.
Translucent:
Break the blank page curse by covering a page with collage or blotchy paint, write your entry on a piece of transluscent paper like vellow or tissue, and affix that over the background so that the textures and colours peak through.
Blank:
Other ways to break the blank page curse could be scribbling on the page before writing, adding light washes of watercolour or other media, a collage of magazine cut outs in small slivers - anything that breaks the blank.
Scatter:
Cut a written piece into its component parts and scatter them over a page that you've covered in paint or collage - or one that's plain and unpatterned.
Keyhole:
Create your written entry, then using a shape (that might have some significance to the text) cut a hole out of it (or a flap) that reveals a specific piece of your text that you'd want to highlight.
Roll with it:
Get a roll of paper and keep your journal on that. Any width will do, but you don't want something so wide it's unwieldly. Try something narrower than the average piece of paper. You could cut portions off as you see fit, glue them into a bound journal, frame them for wall art, or leave them as they are and decorate the tubes you store them in.
