It's nice to have affirmations and record of what you want to focus on in places where you'll see them during the day. Oracle cards are great, but sometimes you want to make something personalized. Sticky notes are fine, but not necessarily pretty.
Most tarot and oracle card decks come with one or two "extra" cards that have either the publisher's name on them or some other marketing information. The backs of the cards are usually quite attractive. You can use these cards to make your own personal collections by hole punching the top, stringing through some appropriately colored yarn, and printing or cutting out words to glue onto the front.
If you don't want to hang them up, they'll look pretty in a basket on a table, or next to the bed in a guest bedroom.
