Where can I find blueprints/instructions on how to build my own wooden swing set?

So I have been planning on buying my son a wooden swing set. After reading the reviews about how the wood they give you is usually cheap and splits etc my husband and I have decided to build our own. Anyone know any websites that have different designs and instructions how to build them? Thanks in advance!|||My husband and I got a kit from the company below. It comes with the plans and the hardware and you supply your own wood. I am SO happy with ours. They also have wooden swing sets that come WITH the wood, but like you said, we wanted to build our own.
