Firstly here is the sketch at Stick it down.
I've used this sketch plus the requirements of Non Traditional colours at 4 crafty chicks and use the colours blue, silver and white at Mystical scrapbooks.
I began by misting the background in turquoise.
Next I used a Kaisercraft mask and texture paste to do the 2 triangles.
I used 2 strips of washi tape either side of the texture paste.
Then I fussy cut the silver butterflies and added the heart.
