Last fall, I did some experimenting with hypertufa, which is cement based, and all my beginner projects made it through the winter just fine. I used old bread pans to make some blocks that are very similar to cobblestone size. The downside I see for doing a whole patio is the curing time, block by block, at temps above 50-55. If you have a place indoors to set them up, unmold them and keep them wet for a couple of weeks, you could build up a good supply of finished "stones". You might want to check out the hypertufa forum here for some info and ideas. I got all my supplies at Home Depot.

You know, I have seen some pretty cool paths and walkways on HGTV where they use old cement chunks that are being thrown away. Like maybe from an old building site or something. I didn't think they would look as nice as they do. But they look terrific. Cheap too!!!

We used the forms your speaking of about 5 years ago. We were pleased with the results and they still look good. We made a path 3ft wide x 20ft long.

My niece ysed these a few years ago and tinted the cement with earthy colors. I thought they were granite until she told me what she had done. Good Luck

We used a Quikcrete "WalkMaker" form for a front walk. It's been in place two years now and looks great. Easy in that we didn't have to prepare the ground other than we removed the turf.
