In fact, I have dozens of them. Bags of vintage cards covered in seam bindings and hem tape. I'm not much of a seam finisher, I use french seams when ever possible to reign in those fuzzy ends.
But I must admit, seam binding made an easy option for what would otherwise be a tricky hem! I bought new fabric this weekend (just what I need, it was on sale! Don't give me that look...) I wanted simple A-line skirt, but I always want pockets! So I cut a pocket opening and a pocket backing. I opted against a hanging pocket since those always ride up on me.
Are you stash building or stash busting? What about using up those old notions?
