I used three of these for this look, all purples. I started with a base using Purple Promise (the dark creme) and Blueberry Muffin (the lilac creme) and then used Marrakesh Nights (the dark purple shimmery one) and some tape for the triangles.
Marrakesh Nights is a bit too dark to really show over Purple Promise in these photos, but in real life it's a bit more visible.
Both the cremes are the usual excellent Jacava quality - Blueberry Muffin is a one coater and I used two for Purple Promise.
I love the Jacava brushes as they're very narrow, which works really well for me, and the long handle makes them really easy to control.
