One of the most useful tools in Photoshop and Photoshop Elements is a feature called Photomerge. As the name suggests, this has been designed for stitching panorama sections together. And it’s done this job well ever since it was first introduced in PSE (then it was upscaled to appear in Photoshop CS). In its original version, the finished Photomerge panoramas were unpredictable and required a lot of fine-tuning to get them perfectly lined up and tone matched.

I call this process a jigsaw panorama. To me it has several advantages over the standard rectilinear frame. Every straight panorama is rectilinear. That's the nature of photography. Everything comes in a rectangular frame. However, if you shoot multiple frames of a set scene, at slightly different angles, randomly if you prefer, the stitched image that’s subsequently produced will have irregular edges. In fact it might even have large parts missing. It just depends on how careful you are when shooting each section.
Aside from a delightful randomness in the resulting shape, you'll soon find that by stitching multiple frames together (and I mean more than six) results in a truly massive picture file. The largest jigsaw panorama I have ever created came to more than 1.5 GB, although I had one student who, memorably, produced a massive 4Gb panorama! He claimed that it took his computer more than three hours to complete.
If you don't want to spend all day waiting for the computer to complete the operation I suggest you lower the resolution, either before you shoot the picture sections, or after using Photoshop Element's batch conversion utility (called Process Multiple Files). Reduce your images to 50 or 70% and then import them back into Photomerge.
Jigsaw Shooting Tips:
Remember to overlap the frames by at least 20%
Do not overlap the frames to much because this just makes the computer have to work harder
Set the lens to manual focus (so the camera does not accidentally re-focus on a near object)
Set the metering to Manual (so the exposures are all the same)
Reduce the file size by 50% to make the processing easier and faster - you will still end up with a large file.

This illustration demonstrates how the frames above overlap, or didn't in this example. I'll just have to go back and reshoot... |
