Haley's blog, then you are on the right track.
For my creation, I did a little bit of a different take on this technique. Instead of using the glitter paper for the "All Lit Up" I chose to use two different colors, black & lagoon, of the shimmer trim (which looks just like strips of glitter paper).
I saw this on Pinterest and have been wanting to try this technique for a while.
Simply take a 4 1/2" x 5 1/4" card base then using wash tape and shimmer trim place them in a diagonal manner. You will see you don't have to worry about making it neat right now:
Then you simply fold all the edges under. You may need to trim around the corners.
Here is the base of the card after folding the edges in.
And here is the final product after adding the sentiment and a few licorice opaques for embellishments.
Supplies used: card base, Teal Shimmer Trim, Black Shimmer Trim, Lagoon Hearts Washi Tape, and Grey Polka Dot Washi Tape (retired), Cloud Nine Stamp Set (from a previous promotion)
