I think marcylove's item falls more into the category of a combination press and mold.
BINGO!!!!
Unusual Small Flower / Leaf Irons These are the tools that were used in the antique millinery, dressmaking, costume-making, and other assorted fabric trades to make beautiful silk and velvet flowers that adorned the fancy hats and clothing of the day. After the fabric was starched it would have been pressed between the two heated halves of these pressing molds to emboss the design. Typically these brass and iron tools are found in much larger sizes. The smallest one here measures about 1 inch and the largest one about 2.5 inches. All three of these small leaf irons are intricately detailed and make for a great display.
