-fusible interfacing (I used high loft) to sandwich between each piece
130" of 1 inch wide bias tape (You can make your own. I was lazy.)
Cut each piece of fabric out, sandwich interfacing between front and back and iron according to package instructions.
Put bias tape on the top of each pocket piece the 30" by 10.5" piece and 30" by 6" piece.
Sandwich two pocket pieces together and baste together on the sides. Mark a line five inches in the front pocket. Sew a line just on the front pocket.
Then attach both pockets to the main piece. Find the half way line and sew through front and back pocket. Then sew bias tape all the way around.
Lift up mattress and place the empty half of the fabric underneath.
