GailG,
Running 8th are a fabric with 8 diffferent panels runing the length of the fabric. Each panel is 5.5" and it is called a running 8th. I found some at wallmart $2.44 yard, that was really nice. Saw some and Joann's 6ish a yard and not as nice.
Wallmart also sold some of the prints in the running 8ths in regular yardage.
