Wow! I was just thinking about doing a tutorial on how to make your own bias tape, when I read Sabra's tutorial (from Sew A Straight Line) on the same thing. So, if you are interested in learning how to make your own bias tape (very useful if you sew much at all), you can check it out here.
Also, if you have never visited her blog before, check it out. I really like it. It has quite a bit of sewing (all sorts of tips and tricks to make things easier) and lots of other things too.
Since Sabra did the bias tape tutorial, I will do a post really soon about several ways to use it.
