|Nancy Zieman - somewhere - said she keeps 1 inch strips of interfacing handy for shirt plackets, a good idea I adopted, storing in a zip lock bag. My added "economy" is that, like all of us, I always have lots of odd bits of fusible interfacing left over that I struggle to keep v. discard. Now I plan how to cut them so that I will have long skinny leftovers - those odd bits are what I cut the 1 inch strips from. When I've used up as much of the leftovers in 1 inch strips as I think reasonable, I finally feel okay to throw away what's left. Those precut strips are often handy- for pocket tops, bias cut fabric hems, and I don't have to dig up a big piece of interfacing, I have the little ziplock bag handy.
