|I have experimented and used Glad Press N Seal to stabilise neck and bias edges on garments, instead of staystitching.
It can be staystitched onto as well, although this may mean removing two strips of it instead of one.
I cut strips, approximately 2.5cms or 1" wide.
It adheres very well to the fabric and definitely stops it from stretching.
Press N Seal can also be cut to the pattern shape, in a similar fashion to a facing.
I simply press the strips firmly onto the fabric, sometimes pressing a ruler on top to make certain I have it firmly adhered, then pin and stitch the garment sections together in the normal way.
Another benefit is that it doesn't gum up the needle with sticky residue.
Pinning and stitching through the Press N Seal is no bother and it tears off easily along the stitching line.
I used Press n Seal to stabilise the armhole edges for raglan sleeves, on Simplicity 4082
Below are some links for two photos I snapped, but didnt include in the review for Simplicity 4082 - Burberry knockoff .
I like to experiment with new products and Glad Press n Seal, has proven to be very useful for stabilising garment edges that will otherwise stretch during construction. I like the fact that it rips away so easily without a trace - specially good when I am making an unlined garment.
I have also used it as a "topping" to prevent loops and pile pushing through stitches, when doing machine embroidery. This works well when there is only one solid outline from which to tear the Press n Seal away from. I don't recommended using it if there are several outlines with fabric gaps inbetween.
I also experimented with it as an extra layer of backing and hooped it with the fabric before doing the machine embroidery.
This is just my experience with the Press n Seal, it may not be everyone's cup of tea. It is relatively inexpensive and a roll of this magic product is useful to keep in your sewing stash.
Press n Seal is not (edited since to add that it is available in some locations) available in Australia - I snapped some up while in the USA, where it seems to be available in most supermarkets and Walmart. Glad trialled it and the only purchasers were quilters, who also use it for transferring quilting designs to their quilts.
Please add your experiences with using Press n Seal as the more uses we find for this product, the better.
