Fabric patriarchal blessing Envelope
You can see a picture of a envelope at this link:
Cut out a rectangular piece of fabric, 13 x 9 inches. Trim one of the 9-inch sides so that the top edge, which will become the flap of the envelope, is curved.
Press down a ¼-inch hem on the straight edge, using the opposite end of the fabric. Press that hem over again to hide the rough edge of the fabric. Sew along the hemline.
Fold the envelope so that 1/3 of the fabric is left as a single thickness to form the flap. Stitch ¼-inch from the right and left edges of the folded material to form a pocket. Trim the hemmed corners at a 45-degree angle to reduce bulk, then turn the envelope inside out so that the seams are on the inside.
Fold the flap sides over two times and press to make flap edges. Sew a seam along the edge. Press the top edge of the envelope down ¼ inch and again, just as you pressed the straight-edged hem. Hem the top edge of the flap.
Add the attachment of your choice, a button, brad or tassel, to finish.
