Everyday things in 3D

I have been thinking that I might tackle some everyday things in 3D creation when I have more time to put into it again. I'm swamped with fixing broken heater and trying to stay warm right now, but when I have that time back, I want to make some stuff that we see every day in street scenes, but never really think about. Such as leashes for dogs, kites for playgrounds and parks, baby strollers and bicycles, skate boards, traffic cones, stop signs and parking meters... just the normal day to day things that we see as we are in the park or driving along, but never think much of as being part of a city or town. Stuff to help people liven up their 3D renders or games a little more.
