For this assignment you will make a yarn that consists of two or more different materials. You should make at least 2 yards of yarn.

Create a page that documents your project. Your page should contain pictures, including one or more microscopic close-ups and one or more regular photos of the yarn. The USB microscope will be attached to the Mac computer in our lab. Write a paragraph or two that describes how your yarn was made and justifies your choice of materials.

Measure and report the following properties (if they are relevant for your yarn):

• diameter (micrometers)
• total length of yarn (meters or yards)
• ply
• fiber length (millimeters)
• twist direction
• twist (turns per inch)
• conductivity (ohms per centimeter or ohms per inch)

Bonus points for measuring any of the following properties and explaining how you did so:

• denier or tex
• yarn size
• tenacity
