The finished size of the envelope is 12" high x 18" wide. You will need about 1 yard of fabric for the top and backing, about 20" x 40" of low-loft batting, bias tape for binding; and threads and stabilizer for embroidery.
Note: We pieced both the top and the lining. If you wish, you can either piece them or make them out of whole pieces of fabric.
Step One: On the fabric that is going to be used for the top, make the embroidery in the center at one of the ends, with the center of the embroidery about 7" from the edge (see the diagram below; X marks the spot for the embroidery).
Step Two: Take away the stabilizer. Press the embroidery through a pressing cloth. On an even surface (table), spread the lining face down, cover it with the batting and cover with the embroidered top, face up. Pin all three layers together.
Step Three: Quilt this sandwich. We made stippling around the embroidery, and "in the ditch" over our patchwork. Press with heavy steam.
Step Four: Square your working piece - make sure that all corners are 90 degrees and all opposite sides are of the same size. The short sides should be about 18" and the long sides about 38".
Step Six: Finish the raw edges with bias tape. Press.
Step Seven: Place the working piece on a table, face down, and fold 12" of the end without the embroidery over (1 and 2 in the picture). Machine stitch both sides (picture 3).
