These would be adorable decoupaged on jars or cans for luminaries (think citronella candles to keep the bugs at bay :)
Think about making a bunting banner with these fun images, you could have flags that say Happy 4th between the images.
Try printing these on Vellum (a semi-sheer paper you can get at the hobby store) and tape them around dollar store vases or candle holders. The images really shine through with a candle behind them.
Are you hanging up paper lanterns? , these would be adorable decoupaged onto white paper lanterns
Try setting these around your table to give it a Vintage Patriotic feel, you can anchor them with seashells, or small stones.
How about gluing the images onto paper cups?
You can even take one of the images to your bakery and they'll turn it into an edible image for a cake :)
I think it'd be fun to tape these onto brown paper bags and fill them with popcorn or chips for munching while watching the fireworks :)
Have a fun filled and Blessed Fourth of July!
