Rhombic Hexecontahedron


2005. Hand stitched. 4 inches tall.

I knew when I saw the piece below that I just had to make one of my own.

Are you ready for some mathematical terminology? At Mathworld you can see an animation of the rhombic hexecontahedron. This is a polyhedron with 60 faces. Each diamond-shaped face is what we mathematicians call a golden rhombus. The smaller angle is about 63 degrees -- that's somewhat larger than the 60-degree diamonds that quilters are used to making.

I cut 60 diamonds from acid-free cardstock, using the pattern I found at the Golden Rhombus site of the previous paragraph. Each side of a diamond is one inch long. I padded each piece of cardboard with batting and stitched fabric over the batting, then handstitched the 60 diamonds together. There are twelve sets of five diamonds. I used six colors altogether.

The rhombic hexecontahedron at the right was given to Barbara Hawk by an antique dealer. The antique dealer paid another dealer $1.00 for it. Barb thinks that the fabrics predate 1930.
Rose decided to make a quilters' version of this mathematical object. She used the quilters' standard 60-degree diamond for hers.
A second one by Rose. She fussy-cut her fabric. Nice effect!
Heather stuffed her rhombic hexecontahedron so that it could be used as a toy.
