I have a small obsession...buttons. Small buttons. The more the better. I started collecting small buttons before eBay and Etsy were around to offer "lots" of small buttons. And as eBay and Etsy came into existence, my obsession was just further enabled.
What exactly is it about buttons? I like just the right amount of realistic detail on my dolls' clothes. Too much is "twee", too little is "blah". The right buttons on a doll cardigan or shoes makes it feel finished. Or if it doesn't, there is still the possibility of playing with the color of thread used to sew the button on. Perle cotton of course.
But buttons can turn a plain grey cardigan into classic vintage, or classic modern, or girly, or rustic. If you don't like the look, you only need to change that last step, the buttons.
