After receiving a comment/question about interfacing's, I thought I'd make a blogpost about it.
First of all, what is the difference between interfacing and facing?
We call the "white stuff" you glue on or sew on, to stiffen an area, "interfacing" and we also call the little pieces you attach to a bodice neckline "front interfacing" and "back interfacing." =) Maybe that is normal or we're just a little confused here.
And to answer your question, Alexandrea, a "rule" I go by in my own sewing, ie, for myself: "If I can do without, I won't do it."
I generally don't use interfacing, ie. in this case "the white stuff" (even though the pattern calls for it). Now if the fabric I was sewing with was lightweight, I may consider doing a strip where I'd be doing the buttons-holes to give them some strength, but other than that, I wouldn't use it.
For instance, a dress that I'm working on called for "the white stuff" on the neckline interfacing's, on a button belt, and maybe in a couple other places, but since the fabric I am using is already on the "sturdy" side, my thinking is, "why use it?" =)
So do you (my readers who sew) use interfacing?
