It’s very likely that you still have lots of Christmas “stuff” around—bits of wrapping paper, holiday greeting cards, ornaments, candles, and so forth.
Why not begin a journal page with a physical object? Find a bit of wrapping paper you really like, or cut up a greeting card, or grab the ornament or candle. In the center of the journal page, tape an image or trace around the object or make a rough drawing of it.
Now, doodle all around what’s in the center of the page. Use stick figures or symbols; draw arrows connecting things. Use stickers or glitter.
Or scatter words all over the page—words that you connect to the image in the center.
What I’m suggesting you do is play with that central image. Have some fun. Use crayons or paints or colored pencils. Use several objects or images and do multiple pages. Stick the verse of a poem or hymn or Scripture in the middle of a page, and doodle it or write it.
You might find that all of this goes even better with hot chocolate. Just a suggestion.
Happy Day after Christmas!
