i'd be interested in starting yet another project. i also have a gazillion old lace hankies. i once had a pattern for keeping the fancy corner and cutting
heart-shaped curves over the corner. then you take the entire "heart" and applique it to a red or pink (in my case, blue) block. the one shown was very pretty. if you do try it, let me know how difficult it is to work with those old fragile hankies. and don't forget pictures along the way. we love pictures.
