YES!!!! that's the one. thanks for finding it. :-)
in class, i'm going to demonstrate a project stuffed with batting. if you don't want to stuff yours, please check these instructions and do as she does up 'til photo 03. that will be where she and i "part ways" because i'm doing a machine only method.
if you'd rather do your cathedral windows as a take-along hand-stitched project, hers is definitely the best way to go.
