The one that I saw Kaye Wood demonstrate, she serged the entire quilt. She laid the backing strip right side up, then the batting strip and then the top strip right side down. She then serged the edge and flipped it back. She warned to be sure and check each step as once you pass a step, you can not go back and correct it with out removing all previous stitching. The next strips are placed in the same fashion, but now you have to lay the batting on top of the top piece so it is sandwiched in between. You are now serging through 6 layers. Anyway I think this is how it is done. I don't have a serger so never tried it, but she did say that it could be done on a regular sewing machine. Maybe she will post the video on her site and I can recheck. As for the time, Yes, it was the 6 hour quilt, not 2 hours, but I think she included cutting time as well.
