DIY hammock with stretchable footbox and knotty mod

I sewed my first hammock DIY project.  This 11' hammock is made from 1.0 oz Hyper D ripstop nylon.  It is double-sided, has a Hangnout's Stretchable Footbox and a Knotty Mod Stretch Side on the opposite side from the footbox.  I sewed some additional D-Rings in the edge channel to be used to attach a bug net and/or a pillow.  Detailed sewing instructions and my pattern can be found below.

LineLocks secure the shock cord on the footbox.

D-Rings are sewn into the edge strip for later use attaching a bug net and/or a pillow.

2. 2 at 28”
3. 2 at 4”

a)      Lining:  Cut 1:  144” length

b)      Edge Strips:  Cut 1:  3” wide strip, trim to 41” length

c)      Footbox:  Cut 1:  13” x 41” elongated half-circle

3)      Assemble hardware:

a)      Cut 8 6” pieces of webbing (seal raw edge with flame).

b)      Slide on D-Rings and LineLocks and then fold webbing in half so that the webbing is 3” long.  Pin into place.

c)      Secure loop with stitching along the cut edges of stich on the overlap in the shape of an X. 

4)      Assemble Outer Fabric for Hammock: 

a)      Sew edge strips using the “continuous binding” method:  with right sides together, sew 3” wide strips together on bias with sufficient length to create 2 144” long continuous 3” wide strips of fabric. 

b)      With right sides together, sew one edge strip onto each side of the outer fabric using a ½” seam allowance.

5)      Assemble Knotty-Mod Side Lining Edge

a)      With right sides together, pin each piece together with hardware in this sequence:  42.5” + D-Ring + 28” + D-Ring + 4” + LineLock + 45” + D-Ring + 28.5.  Hardware should be carefully placed so that it is just inside of where the ½” seam allowance (taking care to note the outward side of the LineLock).  Sew with a ½” seam allowance.  After sewn, flatten out the joining seams with D-Ring webbing facing the head and foot end of the strip and reinforce the webbing with stitching in the shape of an X.

b)      Knotty Mod:  cut one piece of edge strip 42” in length and sew a ½” rolled hem on each 3” edge.  Center on head side lining edge between the hardware with both right-sides facing up and pin in place.

c)      With right sides together, pin Knotty Mod-side lining edge to the edge of the lining fabric.  Sew with a ½” seam allowance. 

6)      Assemble Footbox Side Lining Edge 

a)      Pin together edge pieces in the following sequence: 42.5” + D-Ring + 28” + D-Ring + 4” + LineLock + 3” + 41” Lining Fabric + 3” + D Ring + 28.5”.  Hardware should be carefully placed so that it is just inside of where the ½” seam allowance (taking care to note the outward side of the LineLock).  Sew with a ½” seam allowance.  After sewn, flatten out the joining seams with D-Ring webbing facing the head and foot end of the strip and reinforce the webbing with stitching in the shape of an X.

7)      Assemble Footbox

a)      Fold a ½” double-rolled hem at each square bottom corner of both the outer and lining fabric footbox, taking care to make sure that the folds match when the right sides are placed together.

b)      Pin the lining foot box to the foot side lining fabric edge and sew with a ½” seam alliance. 

c)      Carefully line up the outer fabric footbox to the outer fabric foot side lining edge and attach the outer fabric with a ½” seam allowance.

8)      Attach Lining to Outer Fabric

a)      With right sides together, pin outer fabric and lining fabric together, taking care to make sure that the foot boxes exactly line up with each other and that all edges are squared. 

b)      Sew together with a ½” seam allowance, taking care to skip the rolled hem on the foot box (this will allow the shock cord to exit on each side of the footbox).

c)       Turn fabric right-side out and flatten all seams.

d)      Sew a 1” seam around the arch of the footbox, taking care not to sew through the rolled hem so that the shock cord will be able to exit on each side.

9)      Rolled Hem

a)      At the head end of the hammock along the unfinished edges, pin a 3” double-rolled hem and sew across the edge 3 times (with stitching placed approximately 1/4” apart to reinforce the seam.  Repeat on foot end.
