This is just a guess, but because that is such a long bias edge, they use the iron on to insure that there is not stretch when you sew it. It doesn't sound like the iron on strip is very wide - just enough to stabilize the edge. You will sew through it however when you sew the triangle to the square and it won't be removable. If you don't want to leave it in there, you could try a wash away stabilizer. I've never used one so not sure how it would work. Or just starch very heavily and be very careful not to stretch while sewing. Lots of pins will help keep it from stretching, too.

That is right, it is a long bias edge. On the other piece that uses the interfacing, it states 2 inches wide. I went with skinnier.

OK. I had never seen this technique before, but it makes sense in this application!

The fusible is usually not removable. If you are machine quilting, it will be no problem to machine quilt through it. If you are hand quilting, you might want to find a way to avoid the fusible. If you do have to hand quilt through it, it is going to be more difficult than normal and you might have to quilt one stitch at a time (or stab stitch just in one direction at a time!). It's not impossible to do; just a little harder.

You could try removing the fusible by warming it and peeling it off; I would test that method on the bias edge of some scrap fabric first to make sure it would not distort the seam when you try it. If you are able to successfully remove the fusible, the time to do it would be immediately before layering the quilt sandwich, as you would want to keep that seam stabilized as long as possible.

Here to. I think the interfacing would be a big hassel!!

fusable stablizer stays in- is not removable- unless you purchase one that specifically is made to remove- there are fusable stablizers that are water soluble (wash away) and ones that you cut away- but if it does not say removeable- it's not- if you try to remove one that is permenent it will leave a residue -and possibly cause you to really mess up your block.

The quilt is gooing to be great. Are the instructions asking you to put the F-W along the strips of HST's?

Personally, I think startching would work just as good, like others have said. It is a god idea though if your new to doing bias work or are really afraid of stretching the bias edge. beautiful quilt so far. Show and tell when complete!
peace :D

you must read the directions that came with your iron on interfacing. it sounds permanent to me. not a horrible thing if it's thin and can be sewn through.
