The Extra Long Oblong Hoops gear set is very similar to the Oblong Hoops gear set and is designed to be used in conjunction with the Hoops gear set. This gear set is a collection of extra long oblongs, each of which pairs with one of the hoops from the Hoops gear set.
The extra long oblongs can be used as a simple ring, rolling gears around the inside and making designs that way. They can also be used in conjunction with a hoop that fits snugly between the parallel lines of gear teeth. That hoop can be repositioned between each iteration of a design making for a setup that has precise repositioning rotationally and laterally. This is a style of composition that was first made possible with the Nested Oblong gear set. It is technically more versatile and challenging and can make stunning, complex, compelling art.
The gear set is cut from one 60 cm x 40 cm piece of acrylic and is divided into two 60 cm x 20 cm pieces, each of which contains a set of extra long nested oblongs. Each oblong is marked with the tooth count, prime factors, counting tick marks, center line marker, and a number on the left side of the oblong that denotes what hoop matches it.
