In fact, I have already used this quote to inspire a canvas - some years ago when I was first exploring mixed media stuff. Go here to see the post.
I just love the Lewis Carroll Alice books, and this quote is from Through the Looking-Glass, when Alice first meets the White Queen. To put the quote in context:
‘I’m just one hundred and one, five months and a day.
‘I can’t believe that!’ said Alice.
‘Can’t you?’ the Queen said in a pitying tone. ‘Try again: draw a long breath and shut your eyes.’
Alice laughed. ‘There’s no use trying,’ she said: ‘one can’t believe impossible things.’
‘I daresay you haven’t had much practice,’ said the Queen. ‘When I was your age, I always did it for half-an-hour a day. Why, sometimes I’ve believed in as many as six impossible things before breakfast. There goes the shawl again!’
The brooch had come undone as she spoke, and a sudden gust of wind blew the Queen’s shawl across a little brook. The Queen spread out her arms again, and went flying after it, and this time she succeeded in catching it for herself.
On watercolour paper I've used Acrylic Inks for the background, dripping them randomly onto already wet paper, in the hope that when dry it would suggest where I went next with it! Which was some strange giant flowers or tiny people - you decide!
It's good to believe in impossible things!
