When quilting Halloween quilts, use "glow in the dark" thread. It can be used in either the top of the machine or in the bobbin or both. Include some spiders in your design. To make a spider, begin with a figure 8 with the body larger than the head. Add 4 legs to each side and trail off to another. Your kids and grandkids will not only enjoy their quilts glowing in the dark but will also have fun finding the spiders. (Find "glow in the dark" thread at www.superiorthreads.com)
