It's also a great method for group quilts:
The first one front/back is one my Bee did for a friend back in 2003 who was making a big change in her life. All the blocks were turned in quilted and I just had to put them together. B&W was required for the backings. The sashings weren't all sewn down yet on the back. This one was around 60x72.
The second quilt (front/back) is one we did for a member's first baby. Again, B&W was required for the backing (do you sense a recurring theme in our group?). This time when I put it together, I inset the blocks instead of doing a grid layout. This was done back in 2005. Wow, time flies.
The last picture is one of my favorites of John enjoying his quilt.
It's a great technique.
