making my own hammock - tree huggers

I was too tired last night to stay awake to sew so this morning I an stitching the last part of this vacation's hammock setup.



These tree huggers are modeled after DIY Gear Supply's TreeStraps.  My first strap was 6'4" long and the strap was folded back 6" at each end (they must have given me a couple of extra inches, because i asked for 7' for each strap).  There is about 2 1/2" open at the ends opposed to their 2".

making my own hammock - hammock construction

Pattern

I have been reading Just Jeff's Hiking Page on and off for over a year now.  It was his site that got me interested in sewing my own hammock, actually.  To be extra sure that it will support my weight and in case i ever want to camp somewhere that gets cold at night (not completely unheard of) i have opted to sew the Two Layer Hammock.  Jeff copied Risk's ZHammock.  I did not use a zig-zag stitch, but i did leave the sides open near the ends so i can insert a mat/pad/underquilt if need be.  Risk has some nifty mods to his gear that are food for thought as well, but on this, my first foray into sewing camping gear, i'm going to keep it simple.  I'm not going to start counting ounces but since i am considering trying backpacking someday i do want a lightweight setup, so his mods probably won't be that applicable to me anyway.  But they are shiny.



Construction

The most difficult part of this project was the first seam somehow.  I was delayed even sitting down to start several times and it took me a long time to pin everything into place.  I was hesitant while sewing at first because this fabric is slippery and i had never sewn anything similar before.  Fortunately the dining room table was cleared off and i was able to spread out the fabric to pin it (mostly flat, hanging off the sides and end) otherwise it would have been hopeless.  I did things in a different order than Risk did...i started with the rolled hem at one end (he's got a nifty diagram...i sewed green red red green and omitted blue seams).  I turned it under 1 1/4" twice for a combined 2 1/2" lost at each end.

Then i had to figure out if my machine worked.  It's an old Singer that only sews in a straight line that was once my Grandma's (i'm pretty sure it's one of the machines i learned how to sew on).  Fortunately the manual was still with the case to remind me how to thread it, wind the bobbin, etc., and i was soon able to start with surprisingly good tension.  I sewed once with the folded seam on top once and then again with it turned towards the bottom, trying to sew closer to the edge of the hem the second time.

It isn't pretty, but it's serviceable.  It turns out that the little machine does still work after all these years!  The rubber belt gets a little warm/stinky when sewing/winding at full speed but i had very few issues compared to my other machine that i received as a present when i graduated from junior high.






ready to tackle the side seam
Next i pinned one of the long sides from end to end and measured out the first side seam.  I gave it the same double-run treatment.  Then i pinned the opposite side and sewed it in the same way.  And lastly i pinned the second rolled hem, which required me to trim some of the red/purple fabric away because it was cut slightly longer than the brown.  It was a lot easier for me to pin this second rolled hem than it had been for me to pin the first.

stay/top stitched to imperfection
 The last thing i did was turn the entire hammock right side out.  This required me to pull the hammock through itself.  I stay-stitched all of the seams to reinforce them.  Once again, this came out a lot uglier than i would have liked, but considering that this is the first time i have used Rip Stop Nylon it could have been a lot worse.  The entire project took me less than four hours from start to finish.

Unlike Risk, i did not hem the free edges on the sides of the hammock.  This fabric has salvages with a frayed look but i'm pretty sure that it's not actually fraying, that's just how they were left after the fabric was woven.



Suspension Prep

whip it good
This afternoon i whipped the ends of the hammock as outlined by Just Jeff.  I'm happy with my knot but am surprised by how much of the hem is sticking out above the whipping.  It feels like a lot, and definitely looks thicker than the hammock in Jeff's examples (which is because it's double-thick, of course).  Tree huggers are on the menu tonight, and hopefully my first hang will be Tuesday night.

Now i know that i said in my last post that i'm saving ~$60, but this isn't strictly true.  That is $60 is i went with a barebones, less-than-ideal setup.  To buy a similar hammock at REI that apparently doesn't work right with the pad inserted it would cost me $95.  I paid $42 for my hammock materials, an additional savings of $43 were i to buy the hammock that's most similar to what i'm sewing.  So of course if you consider what i would have bought if money were no option...i might have chosen just to buy a Hennessy.  In that case the bug net, tarp, and snakeskins would have been included, but i would be saving even more money by customizing my setup.  This also means that if something wears out i can fix or replace what is broken rather than the entire hammock tent.

making my own hammock - materials

So i have been happily sleeping in a hammock for a year now (yay!).  The only drawback to sleeping in a hammock is that the frame in my room if huge and takes up so much space.  Also, the material that my hammock was constructed with (string) is fragile.  I have had to repair breaks several times after snagging on a button on my pants/shorts or one of the bolts on the frame.  One must be careful with these things!  The miracle is that this frame (that i made with my own two hands!) and this hammock hold me up every night and mostly seems like new.

Well much as i'd like to i can't lug my hammock and its frame out camping with me.  I knew this would be the case, and started planning to buy or sew a camping hammock even while i was buying and hanging my first hammock.  I bought some straps to make my own tree huggers at the same time that i was buying the materials to build the frame.  So today i'm taking the plunge and am going to start sewing my camping hammock!

To start out with...i debated whether it would just be easier to go to REI and buy one pre-made.  I read reviews, i agonized over it, but i finally decided just to make it myself.  Money and color were both factors in this (i do not want a camo hammock, and i'm not sure i want one that's lime green or royal blue or red, either).  As a result i was able to pick out the colors i wanted to use (subdued but still slightly feminine) and i got a great deal because the local fabric store was having a sale...they were closing up shop and moving to a smaller location that is only for sewing machines and quilt fabric (rather than the mega-fabric, mega-home decor fabric location they had been).

Hammock Material
6 yds ripstop nylon = $27.50 (3 yds each of two different colors, 54" wide)
25 yds nylon cord = $1.70 (for whipping hammock...no way i'll need this much)
1 spool Gutermann thread = $2.70 (100% polyester, recommended for sewing tents)

Mosquito Net/Snakeskin Materials
8 yds netting = $23.75 (in an off-white...taking a chance here)
1 110" Boat Zipper = $10.75

Tree Hugger
straps - two 7'x1.5" = $5
40 yds climbing rope = $8.25 (couldn't find Spectra rope in town or online for a reasonable price)

Tent
Kelty Noah's Tarp - 9'x9'= $49
Paracord = $13 for 100yds (won't need that much!)
Figure 9 rope tightener w/6' guy line x 2 - $7.50 (for tarp ties)
Tent Stakes x 4 = $10

Grand Total = just under $160



As you may have deduced, i decided to take the plunge and get an REI membership.  I'm not sure it's going to pay for itself this year, but the guarantee made it tempting to buy the Kelty Tarp through REI rather than Amazon even though it costs ~$10 more.  Half of that difference would have been made back at the end of the year with the member's refund.  Unfortunately the tarp was backordered through REI so i'm going with Amazon instead and hoping it arrives before it's time to go on the trip in ~3 weeks.

In case you're wondering if this setup saves money...refer to REI's selection of hammocks and realize that i have to have a setup that can hold more weight than some of the cheaper hammocks are rated for...and you still have to buy things individually (hammock + bug net + tent + tree huggers).  My tree huggers cost $5 compared to $20-25.  I am saving at least $60 by my estimates.

I will continue to edit this post while i am still working on this project.
