I then use Wrights Extra Wide Double Fold Bias Tape (available at any sewing store, Walmart, etc.) to string the pennants together. I tried pinning once, but it was more of a pain then a help. I've found it much easier to tuck the top (unsewn) edge of the pennants inside the fold of the Bias Tape and sew across the bottom edge of the tape, sewing the pennant in the process. As I get about an inch and a half away from the end of the pennant, I insert the next pennant, overlapping about an inch and continue sewing the tape shut across the top of the triangle.
If you're interested in other sewing tutorials, I've got a bunch. Please stop by and say Hello!
