We're working on several interlocking paver patios at our house this spring so we know you are thinking about them at yours! 
We are creating several small ones just big enough for a couple of chairs and a table to enjoy the outside as our children play in different areas around the farm.  They don't stay in one spot!  And we have to have a comfortable spot to sit out.  Looks like we'll be outside much of the summer.We are using several different types of pavers for each patio.  The benefit of small patio areas is the opportunity to use remanant lots from dealers.
