Has anyone seen and/or used the new "stubby" presser foot? It was demonstrated at the quilt show and is also in Nancy Zimmers new catalog. No need to pin curves when piecing! She made it look super easy, but its $30.00. So I'd like to know if anyone has tried it. The shortness of the foot itself is suppose to make going around curves a snap, but maybe she practiced for 10 years (LOL) before she started demonstrating it.
