I'm not a good enough drawer to catch their likeness whilst they're flitting about, so I've copied an image from a book. I had no idea how complex all those feather patterns were!
I drew the wren onto caligraphy paper (a new purchase - I was eager to try it out!) but I think I used the wrong side as it has a slightly rough surface, whereas the other is smooth. Never mind, it still worked well with pencil.
Having stuck the finished paper to my canvas using acrylic gel, I thought it needed something else. I drew a circle and used gold acrylic paint to infill. I could have used gold leaf which would have looked even better I think, but I couldn't get the lid off the size.
I liked the sparseness of the white and gold with the pencil drawing, but decided to be reckless and add a spot of blue.
Of course, once the blue had dried, I decided I preferred the white!! I compromised by putting a coat or two of white acrylic over the blue except for the bottom right hand corner. Why did I leave that? I have no idea - I just liked the weight of colour at the bottom and the design made by the blocks of colour.
