Then I totally urge you to take a few moments to surf around the 'net for some "How To" sites and bookmark them, maybe print out a page or two for reference, or pick up a basic sewing book when you get the bias tape.

Bias tape is a long strip of woven fabric cut so that the threads run diagonally across the strip at a 45 degree angle. This angle is called the Bias. Bias tape comes folded "single" or "double". Single fold bias tape has the long, raw edges pressed and folded under. This is the kind you want, in a wide width (Blanket binding will also work). Double fold bias tape is wide, single fold tape folded in half again. This will also work, if the second fold is unfolded so the strip lies flat with only the raw edges folded in. It might cost more than single fold.

Look for bias tape in packages by the zippers and threads. You'll see lots of other cool things there, like twill tape which is sturdy and great for laces, ties & re-enforcing, seam binding which is satiny and ribbon like and can be used as ribbon, and blanket binding, which is wide satin strips (not bias) with the edges folded in.

Oh, and speaking of Bias - Woven fabrics will not stretch sideways or lengthwise. But when tilted at that magic 45 degree bias - they DO stretch! So the bias tape also has a bit of stretch to it, allowing it to go around curves without puckering (much, in theory).
