What is your favourite colour? Mine is white! I drive a white car, and if I could, I would have my whole house in white. That, unfortunately, is not possible with 4 cats and 2 dogs.
Funny thing is, I hardly ever crochet in white. As much as I love it, when it comes to crochet, it's just, well, boring!
I cannot say that I have a favourite colour for crochet. It is determined by whatever or rather whoever I am doing the piece for. Most of my crochet lately has been in light pastel colours.
Last year, a lot of crocheting was done for a beautiful little girl that was born in October. So there were lots of shades of pink and pastels.
Now we have another baby on it's way, but seeing that the gender is a surprise, I'm doing lots of 'neutral' colours. Lime, green, yellow, beige.
