Fabriclarge enough to cover your iPad - cotton works best
2rollsDuck Tapetwo patterns
Adhesive Velcro squares
Instructions
Lay out the fabric with the iPad on top. Draw around your iPad with the ruler, leaving about 1/4" on all sides, except for the top flap. The top flap should be long enough to fold over (I left 1").
You should also create a piece for the front of your iPad. Draw another piece using the ruler. Cut all pieces out with scissors.
Cover the back side of the fabric pieces with your main pattern of Duck Tape, overlapping slightly.
If the Duck Tape overlaps the edge of the fabric, trim with a craft knife. It also gets rid of any cruddy edges on the fabric edge.
Cut five lengths of a second pattern or color of tape to fit all around the edges of the iPad sleeve. Cut each piece in half using a craft knife. You'll use these strips to go around the edges. You'll need: two long enough to go down each side, one to go across the bottom, one to go across the very top flap, one to go across the top of the case at the front.
Place the Duck Tape on all the edges of the case, fold over to start securing the case. You'll work all the way around, securing the front to the back.
At the very top where the flap is, make a notch with the craft knife before folding the tape over.
Adhere the Velcro pieces at the top of the flap and on the front of the case to finish.
Notes
I cut my fabric in one large piece, with a flap that came down, and a side piece that folded in.
