A couple of years ago Skittl1321 posted a thread called Single-fold bias tape ... Why?, which got me thinking... the only sort of bias tape I've ever made/used is the single-fold kind--used either to bind things, or applied as stripes (as shown here in a clearly binding-happy project!), or made into piping.
...So what's the purpose of the extra fold down the center in double-fold tape? It doesn't seem to help when binding, since it shows up as an unsightly crease if it's not precisely centered on the edge of what you're binding... and you certainly don't want it when applying the tape flat. But since it's so common, what's it for?
(Evidently I participated in that earlier thread, and while I'm clearly by no means a binding expert, it is something I'm slowly coming to *really* enjoy.)

Yes, one-step binding, which has NEVER worked well for me.
But double-fold commercial tape does provide useful folds for a 2-step technique for sewing bias tape and evenly binding an edge. If this is not the type of binding that you are doing, then I'd have to agree that double-fold bias tape isn't all that useful.
Ugh, I need to define some stuff beforehand to make this clearer: Let's call the the first two folds (which give you single fold bias tape) as Fold-1. Let's call the fold down the middle of the tape Fold-2.
If you take a close look at the commercial tapes (Wrights), you'll see that the fold down the middle (Fold-2) is not exactly in the middle. Once side is slightly "shorter" or "narrower" than the other, and the edge of Fold-1 on the second side "sticks out" slightly.
To make the best use of this, open Fold-1 on the narrower fold of the tape. Lay the raw edge of the unfolded side of the tape so that it is even with the edge of the object you want to bind (for example, the outer edge of a baby bib).
Stitch in the well of the fold.
Now wrap the tape around the edge of the project. Fold-2, down the middle of the tape, should now fall exactly on the edge of the project AND the edge of Fold-1 on the wider side of the tape will extend on the other side of the project just beyond the stitching line.
Now you can stitch in the well of the seam you just sewed and catch Fold-1 of the wider side in the stitching.
Because Wrights is a poly-cotton blend, and I suspect it's been treated with sizing or something to keep it fairly stiff, it's possible to do this 2-step process without pinning anything, just line up the raw edge of the tape as you are doing that first line of stitching.
If you want to try 1-step binding, you will probably have better results if you have the narrower side of the tape UP, facing you, as you stitch.
