This might be an old trick to you appliquers out there, but I just learned it from one of my students yesterday while giving a workshop on my "Pretty Crazy" pattern at our delightful local quilt shop in Camas, Washginton: RiverQuilts.
Yes, I said "learned this from one of my students". That is one of the many rewards of teaching--I always come home with new knowledge!
The Pretty Crazy pattern calls for lots of fabric strips with ironed under edges. Marie showed us an easy and great way to iron under those edges in a perfectly straight line, without burning your fingers.
like this one, and a hard surface.
I didn't get a shot of the ironed strip, but you know it turned out perfect.
