One of the ladies I work with has just inherited some beautiful antique jewelry. One of the pieces is a brooch that you use for a teeny, tiny piece of needlework. She has asked me to stitch a flower for her. I have been stitching for years, so I'm not afraid to try, but unsure. Would you recommend 40 count linen or silk gauze? With the gauze, would I have to stitch a "background"? Any response would be appreciated?
