Honestly, the hardest part was testing the type of batting or interfacing to get the right amount of support so it wouldn't curl against a wall. I tested Floriani's Stitch and Shape, Pellons's Flex-Foam and light weight polyester batting. I ended up fusing Decor Bond to the fabric and the polyester batting as a filler. Stitch and Shape sews like a dream but is very rigid and doesn't bend in a seam allowance. I will save that product for a tote bag or portfolio cover. The Flex Foam was simply too thick. I wanted the wall hanging to be somewhat stiff so it wouldn't curl with a softer appearance.
I decided to add a rod pocket to the top and bottom so I could insert a thin wood slat or dowel rod if I needed it. The wall hanging measures 15x17". (Sorry, I put buttons over their faces for privacy.) I embroidered Christmas 2016 with the built in font on my 830 and reduced the size to 80%. I didn't use a separate software program which saved me quite a bit of time. This size photo quilt would also look great in a frame.
