1 - Take plastic bottle and cut the top off 65mm (2 1/2 inches from the base of the mouth). Set aside. Discard the bottom portion.

 

2 - Set up your sewing machine for a straight stitch. Double over the fabic so that you have a strip 240cm long x 7cm wide. Run a stitch about 15mm in from the open edge. Run a second stitch 8mm from the open edge forming a tube. Flip the fabric tube inside out. Set aside.

 

3 -  Using a 360ml plastic container, combine 1 part cement and 3 parts sand mix with a trowel. Add 1/2 - 1 part water and mix thoroughly until all the water has been evenly dispersed thoughtout the mixture.

 

4 - Taking the tube in your left hand put the mouth of the bottle top into the tube opening, like a funnel. Hold the tube and funnel and begin adding the concrete mixture with the spoon into the funnel, working it into the tube. As you load the mixture into the tube you'll notice that it may not go all the way to the bottom. When this happens shake the tube until all the concrete comes to the bottom. This may cause a lot of liquid to spray thorought the fabric. If this is a concern please cover surfaces with plastic sheeting.

 

5 - Once the tube is approx 140cm filled tie off the end. At this point you can build a support structure to drape the sausage of concrete over. Make sure this is set in a place where is can remained undisturbed for up to 3-4 days.

 

6 - Seem side up, lay the sausage on a flat surface and wrap it over the support structure so that you create a triangle about 40cm on each side. The ends should overlap by about 10-15cm at the top. Once the shape of the sculpture is settled leave it for 3-4 days.
