2D quilling - an extra dimension?

It's always fascinating to look at other quillers' work, and the various blogs I follow are a constant source of inspiration to me. Many of the projects  I most admire use layers of quilling to create texture and depth - but, because my quilling mostly ends up on greetings cards, it isn't always practical to adopt this particular approach.  Here in the UK, any item thicker than 5mm incurs an extra postage charge, so a design which has coils glued on top of one another is much more expensive to mail. (Not only that, but multi-layer designs can so easily get damaged in transit as well.)

Regular followers of Quilliance will know that I've recently started experimenting with using photos of quilling to produce a low-cost range of Christmas cards. (They're proving popular, by the way, and I've sold several packs already!) But this week I've had another idea: why not create the illusion of extra depth by putting real quilling on top of a photo of quilling?

So I started by creating this quilled motif (it's intended to be vaguely suggestive of an unfurling bud/leaves), which I have photographed for use as a background:

I printed this photo on to a card, and then added some 'real' quilling to look like a flower on top:

Voila! A design which looks just like multi-layered quilling, but without the physical extra depth which the real thing would have entailed. Using this technique I can use the same background for many different flower designs, and it will save time, too, because I've only actually had to quill it once!

Is this a useful new dimension in terms of 2D quilling? I'll be interested to hear what people think!
