Cut fabric 86" long, 60" width at the head end with a taper down to 50" at the foot end. Marked a 2 inch seam allowance around all edges and drew baffle chambers 6" apart. Rolled my no-see-um into a tube and made marks down the tube every 3". Used a straight edge and rotary cutter to cut on those marks which gave me some really straight baffles. Single fold hem the baffles when sewing into the inner and outer shell. I stuffed 1 oz of 850 FP down in each chamber then rolled hemmed the side. Sewed a draw string channel in the foot end and added 12 grosgrain loops (6 on each side) to create a lace up foot box. Final dimensions are 76" L x 56" W (head) x 48" W (foot).
Weight: 25.2 ounces.
