The glycerin glue is made by putting 6 tablespoons of water in a pan.  Bring it to a boil, remove from heat and completely dissolve 2 packets of unflavored gelatin.  Once the gelatin is dissolved, add 2 teaspoons of liquid glycerin, 2 tablespoons of vinegar and stir.  Pour into a seal tight jar.  This glue will become gelatinous when cool, just heat it up in the microwave for 10 seconds or put the jar in hot water, to use it.

The table and stools should be safe for normal use and hopefully last for a long time.  The upholstered chair should work fine if the seat back is against a wall.  By itself, the chair back will likely fail.  The seat of the chair is strong enough to support two adults and will be safe for routine use.

The upholstered chair will be donated to an appropriate technology instructor, and used by his students for office hours.  The client specified a chair that was comfortable enough for 20 to 30 minute sessions.  The chair will be used several times a day by different individuals, and will be moved throughout the office, therefore, the chair must be durable enough to withstand this type of stress.  The office is newly remodeled and the chair should reflect professional quality along with a neutral color scheme.  The client specified having a chair with low embodied energy as a priority.  Despite being upholstered, the client would like some of the cardboard exposed to show what the chair is made of.

Budget: This is the budget for what we anticipate spending on the furniture. We will try to find most of our materials through a donation process or by utilizing Thrift Stores, so the costs are subject to change.

Budget: This is our final budget. We did purchase other materials for testing which glue we wanted, but those costs are not included since we decided to use rice.

Originally, the chair was going to be a series of cut cardboard glued together to provide a solid frame, similar to the stools.  The shape of the frame required our largest pieces of cardboard, and we needed to be able to use some of the large pieces on the table and stools.  The design was changed.  Instead of a bunch of pieces glued together, the frame was made up of 13 2-ply ribs, hand cut, spaced 2 inches apart.  The ribs were notched and are held in place by 6 notched bracing members.  There are 2 bracing members in the chair back, 2 on the bottom and 2 on the seat.  The bracing members are 26 inches long, 4 inches wide and 1.5 inches thick.  They were made by gluing 15 pieces of cardboard together and then cut to the above dimensions with hand held jig saw.  During the dry fit, the ribs and bracing members held tight enough, that it was decided glue would be unnecessary.  Once the frame was together, 3 plies of cardboard was glued to the seat and seat back.

The stools were made by gluing 16 inch by 19 inch hand cut pieces of cardboard together.  Some pieces were two ply and other one ply.  The plies were alternated 90 degrees on every piece.  One stool has 68 pieces and the other has 78 pieces.  The stools have different thicknesses, 14 inches and 15.5 inches.  The sides of the stools were decorated with a decoupage of appropriate technology pictures, using glycerin based glue.

The cotton insulation works well as a seat cushion, but I would recommend using a 6 inch thick piece or two 4 inch thick pieces.  The insulation used was from a 4 inch thick piece and you can feel the hard portion of the seat.  Overall, cotton insulation is an excellent alternative to foam cushioning.  The biggest test for the upholstery fabric is the test of time.  I am curious to see how well the fabric holds up, as well as the hand sewn seams.

My original goal was to create chair out of environmentally friendly or reused products that would be indistinguishable from a designer chair.  The chair fails in this regard, but I’m still proud of the end result.  I’m confident that with what I’ve learned and with more practice I could create really nice furniture.  I’ve never made a chair before, so this is my prototype.  If I were to make another, it would be much nicer, and incorporate all that I’ve learned from this experience.

Originally, I wanted to build chairs similar to Frank Gehry’s design but that proved to be very difficultSo I settled on just making stools.  The table took some figuring out, which I am very grateful for Miles Smith’s help in that.  Once he showed me how to fold the table properly to get an edge underneath to attach the stem, it went quite well and was easy to assemble.
 +
I was very pleased with the way the table and stools turned out.  I was especially happy that I was able to retrieve most of my materials from the waste stream, to keep my project sustainable.  The only things I had to buy were the Borax, paint brushes, glycerin, gelatin, and box cutter blades.  If I had not decorated it, the entire project would have only cost me $10.79 for the brushes, blades and Borax.
 +
It was very easy to build, it just took time.  The cardboard is strong enough to enjoy the table and stools for a very long time, as long as it doesn't get wet or there is a fire.  Be creative and have fun with building eco-friendly and stylish furniture for your home. 
 +
 
 +
<font color="red">'''Warnings''':</font>
 +
*Drink lots of water and wear gloves while working with the cardboard, it dehydrated me severely.
 +
*Put as much pressure on your glued product as you can, especially on the corners.  We used two 100 lb bags of sand and piled things on top and I still had issues with the corners.
 +
*Make sure that you let the glue dry thoroughly before use.
 +
*Don not use the furniture in rooms where the floor gets wet often.
