Perfect hem line - draw a line on card stock, 1 inch in from edge of card stock. Place the card stock on fabric, with line parallel to fabric edge. Fold fabric over card stock, aligning fabric edge with line; press with an iron.
This is called a 'ring base' because you can attach anything to it from a simple button to a large fabric flower. So simple but you can make it absolutely GORGEOUS by what you attach. I may do this with some fabric scraps. If I do - I'll be sure to post ♥
