* Figure out your finished width of fabric. This measurement will not include seam allowances but you will be adding those to the total width for cutting later. In other words I had a 54 inch width. With two half inch SAs I would have a FINISHED WIDTH of 53 inches. Hold that number!
* Get yourself some adding machine tape or a very long strip of paper taped together. Make it at least three inches wide. Cut it to the FINISHED WIDTH of the valance, in this case 53 inchs.
* So here is Card 2 with seam allowances added to the top edge. Take a ruler and line it up with the bottom edge of the finished scallop, the scallop line closer to the bottom of the card. Mark two spots equidistant from the bottom edge on the left and right sides and the same distance away from the lowest point of the finished scallop. Put a tiny notch on this side, where the arrows are.
Now all I have to do is cut my lining the same size and stitch it up pillowcase style, easy peasy. I'll show you how I do the loops and bows when I get to that. I need to buy some lining in town tomorrow. I don't even have an old sheet I can scrounge. Any questions, let me know.
This technique would also work nicely for hems on a skirt ...Don't forget Thing One and Thing Two, oh, I meant to say Card.....Bunny
