Here's a small fabric sample that I'm creating a hem on. I've turned the raw edge up 1/2" and from there I'm going to turn it up a full inch meaning that my hem allowance in this case was 1 1/2".
Apply the fusible web with the webby side down on the fabric. For some webs you'll steam or iron it in place and for some, like the Wonder Tape, you just stick it on there and push it down. For my sample here, I've turned the 1" portion of my hem allowance back and I'm applying it to the inside of what will become my hem.
Once you have the web in the place you want it, lift up the paper. For the Wonder Tape, this might be a bit tricky but just separate it carefully at the top and away you can go.
Now stick the remaining adhesive side to something else. In this case, I'm just turning up the hem that 1 inch and sticking it to the other side. Keep in mind though that this can be helpful for zippers, trims and other such things. You'll press with steam in the place with your iron and then from there permanently stitch in place. Remember the fusible web is just a temporary baster. It keeps things from shifting about and makes sewing certain things together easier. The final step is permanently stitching whatever you've temporarily basted.
So, what are some other applications that you might use this stuff in? I've just shown a hemline here and zippers which you can see in my Craftsy class. Some other places to consider is matching plaids and patterns on fabric. Instead of hand basting these sections, try the fusible web instead. One of my favorite places to use this is in the collar stand area on a classic button up shirt - in fact I'll show this one in an upcoming tutorial. Easy peasy! Another favorite application: Whenever I have to stitch in the ditch, like in the case of a skirt or pant waistband, I put this stuff down on the inside/facing first and then go about stitching in the ditch. Prevents rippling, pulling, puckers and distortion. So much easier! I also used it in the neckline binding of my wrap dress version from the 2-in-1 sewalong.
