1) Two pieces of 1.1 calendared nylon cut to 52" x 77"
2) I added the material from the 8" wide scrap to the ends to make the quilt a bit longer. (as seen by the multi colored stripes.) I used a felled hem seam.
3) Hem the two pieces respectively.
4) mark baffle lines with painters tape. Be sure its on the shiny side (Inside)
5) Sew one long edge together by wrapping the inner shell about 1.5" over the outer shell. Aim for a roughly 1" channel that will be used for the suspension.
6) Sew the baffling to the other shell. Imagine your sewed edge as the spine of a book that you are slowly closing. Sewing the baffling across from the sewn edge out. its helpful to roll the respective shells so that only one baffle line is exposed at a time. (beer optional)
7) Once all of the baffles are sewn, sew the remaining long side (leaving a cord channel) and one of the short sides in the same fashion.
8) Add down. I used a cardboard tube that was zeroed to a scale to maintain an equal distribution.
9) Sew final short end closed. Don't forget to make the fold over channel!
10. Feed suspension through the channels.
