This is also my current favorite.

The actual joining method starts with the posting text: "Now you need to prepare your joining strips..."
This technique adds a 1/2" (finished) sashing between the blocks. I actually reverse the strips, putting the folded strip on the back. I usually piece some blocks and add 1/2" sashing until I get a section that's about 2 or 3 feet square. I sandwich this section and quilt. After I get all my sections quilted i join the sections with the method above.
Here's a link to my last set of quilts that I did with this method.

you can't tell on the front which sashings are just sashing and which are joining strips. I think I did these in 5 or 6 sections.
The only method I know of where you don't have a sashing used in joining the sections is the lap quilting method by Georgia Bonesteel. That's how I did my avatar. It requires some hand work.
Hope I didn't confuse you more.
