I was thinkin' I'd croshay a skull applique' but after lookin' at a pile of lace doilies in my sewing room, the lil' lightbulb in my head went poof!
You can use a thrifted lace curtain or old lace blouse. Whatever. Find a lace panel of some sort.
Then, I cut up some thrifted doilies for the eyes, nose and mouth and hand stitched them to the lace skull. I had a floral lace applique which I used as the hair.
I used embroidery floss to blanket stitch the skull to the front of the tee.
