I love things with holes, for I can put things/images in there and make nice jewelry pieces out of it, and I feel the urge to do brooches with hanging things, similar to trees' branches.
Maybe it's all due to the fact that I love 'hanging in there': uncertainty is the only way to be for me, it seems, so I feel at ease with it.
I have also always loved the swings on the playground. Posts about my 'swinging nature' were among the very first ones on this blog, but I could add some extra images here. And, boy, don't I have more than enough: pretty much every time I am near a swing I go for a 'ride' and take a picture, so I have plenty of photos from all over the world.
Here are some - mine and other people's.
