Geometric sewing

My recycling tendensies has found a peak in the tetraeds. It is a good way of cleaning the craft closet too. All old zippers that I have collected and pieces of ribbon, lace and fabric turn into something quite useful. Bathroom stuff, knitting projects, keys, you name it - anything that needs a home gets a home in a tetraed. The leftover fabrics from making the tetraeds go into the patch work box.

When you cut out the fabric for a tetraed, don't forget that the edge between to sides is 8/7 times the lengt of the zipper. Cut 2 times the length of the zipper as the long side, and 8/7 times the zipper length as the short side (2*zipper X 8/7*zipper) - otherwise the length of the side wont be the same. In the model I make, the zipper goes from the top down to a middle of the base on one side. It is actually very easy to make a tetraed, the trickiest part is to add the zipper, and if you want to do lining you need to do some abstract thinking.
