Here's a craft I completed a few weeks ago for my Etsy shop.
Today I had an inspiration to put them on some Kraft card stock that I use for my shop tags. I'm always trying to perfect my packaging while keeping it simple and plastic-free, and I'm very drawn to the natural look of Kraft paper and boxes.
I also did a listing with these in a mason jar, which I LOVED as well, but the colors get muted just a tad through the glass so you can't see how vibrant they are until you open it up.
Whoever invented the rainbow is a GENIUS!
