Alternate side looping is my favorite quilling technique so I folded ASL leaves in a variety of sizes and filled in with shaped teardrop coils.
A cool thing about gilded white paper is that the metallic shine is clearly visible when looked at straight on or if a light shines on it from above, but from the side, as you see in the photos below, it mainly appears white.
Choosing a mat proved to to be the biggest challenge as the color of the invitation leaves was chameleon-like. I would study them and think 'oh that's gray' but with the next glance I was sure they were brown!
Luckily my reliable frame shop had just stocked a line of mat board with an elegant sheen. It married well (pun!) with the dressy invitation and was even available in a color that solved the grey/brown conundrum.
