Ornaments without beads

I do not limit myself to beaded ornaments.  One of the first ornaments we did in art class was constructing an icosahedron, a solid made up of 20 equilateral triangles.  Using 1 inch circles we scored the triangle onto the circle, bent the flaps up and then filled the triangle with Christmas images.  Then we glued the 20 parts together to form the ornament. 
 



A couple years ago I did a cube with rhomboids instead of squares.  The Platonic solids are 3-D shapes made from same size equilateral triangles, squares, and equilateral pentagons.  There are only 5 solids which can be made using these geometric shapes.  When you start looking at using shapes such as rhomboids, isoceles triangles, and diamonds, the solids morph into additional shapes.  When you start mixing shapes you get an even more diverse set of 3 dimensional shapes, known as the Archimedean Solids, one of which is the shape of the soccer ball, made up of hexagons and pentagons.






It is nice to have friends who have industrial lasers.

Other ornaments which I have designed use acrylic plastic that is cut with an industrial laser and then joined together around a central axis to form 3 dimensional ornaments.  Sometimes it is fun to be ADD.  I have over 25 designs in this genre.  I use 2 discs which are cut with recessed areas to allow alignment and gluing.  The discs also have a small circle cut in their middle to allow for a headpin to act as a point of attachment for the chain.  (OK, I admit I use a bead in each side of the disk to help with the balance.)
