Due: Tuesday March 1, 2011
See student yarns here

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 (talk to Leah if your yarn is so labor intensive to build that this requirement seems unreasonable). Create a post that documents your project and put your post into the “Yarn” category. 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 iMac computer in the HLT lab. Write a paragraph or two that describes how your yarn was made and justifies your choice of materials. See the yarn built by year’s class here.

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
• elongation
• elastic recovery
• absorbency

Bring your yarn to class on March 1 for demos!
