The Library Challenge is an interesting one. The challenge is based on a book cover, and you can use the cover art, the title, or the story as your inspiration. In this case, I'm using the title.
Not long ago I purchased two dies from Reverse Confetti: the "On the Curve" cover plate, and "Over the Rainbow." The design team for Reverse Confetti highlighted multiple ways to creatively use the cover plate, and I'm always looking for interesting dies that might appeal to grandchildren. A rainbow seemed like a good choice. As it turns out, my first card with these dies went to an adult cousin who loved it!
Admittedly, it took a bit of time to cut the cover plate from so many different colors of cardstock, but I now have a stash of bright colors all cut for the next card. Once I had the colored pieces, I die cut the cover plate from Select White cardstock and inlaid all the pieces. This was made much easier by applying a sheet of Stick It behind the die so that each strip immediately adheres to the background.
The next step was to die cut the cute clouds and sun from the "Over the Rainbow" set, which does include the die for a much smaller rainbow. I did some ink blending around the sun rays and popped up the center of the sun and the clouds on the cardbase. The sentiment is from Simon Says "Best Ever" set which I curved on an acrylic block to add to one of the rainbow stripes. I'm pretty sure I'll be using these dies for birthday cards as well as thinking of you cards. Who could resist smiling at such a bright and cheery card?
