I've used that technique on this card for Try it on Tuesday.
Here's my card which features Collage as the requirement.
I started with pale pink(not white as it appears) cardstock.
On that I've pasted pink polkadot paper then stamped using a Kaiser stamp saying "memories" and "remember". To the RHS I pasted a scrap of pink star paper.
The heart at the top is vellum painted with pink paint then cut to shape.
The leaves are canvas.
The pink ribbon and strip of washi tape across the centre help to finish it off. The bottom row of washi and white satin ribbon are straight.
This is the pleated technique I referred to.
