DD loves owls, and I googled for owl fabric to make her some curtains and came across a website that has the most beautiful fabrics, but they're meant for quilting/blankets etc. I can't quite get the idea in my head of how big the patterns are, so could anyone who knows about this take a look and see if these patterns would be headache inducing in a curtain size? I'm finding it very hard to imagine a large expanse from just the little pictures on the screen, so maybe someone who is used to working with this sort of material might be able to explain how it might work out. They would have blackout linings, so thickness of fabric wouldn't be an issue hopefully.
The third fabric may be a bit overwhelming because of the dark colour.
If you are worried about the curtains being busy, why not think about having a neutral coloured curtain with a deep border at the bottom in the owl print?
You could see if you could order a 'fat quarter' - a small square of the fabric. It would give you an idea of the pattern size but is big enough to make accessories like a draw string bag so wouldn't go to waste.
