I used a mask I got free with a magazine, it didn't turn out like I expected - the paint wad a bit too thick for the pattern using a paint brush, so I used a tiny bit of sponge and dabbed through the mask instead, end result more likd I wanted.
Rooting around in my butterfly drawer, I came acrosss a holographic peel off sticker I received years ago in a swap which fit perfectly in the middle of the design, also used the 4 matching butterflies in the corners.
The butterfly topper is part of a Sizzix die set which I won a few challenges ago. I accidently put a hole through it when i was peeling it away from the die, hence the blue gems.
The only thing I didn't do was the Glossy accents part of the challenge.
