A few examples exhibited 1/4" instead of the commonly used 1/2" straight warp. This was an "extra credit" option and many selected it. As you can see here, the smaller weft allows the visibility of more color.

It is more difficult to do with soft material like contruction paper. The challenge however, was well received.

From the examples shown it it is noticed that colored backgrounds were preferred, blue being the most popular. The next sections are very different!
