Make sure that your fabric is folded in half.
Pin your pattern so that one of the longs sides of the pattern is on the fold.
Cut out the other three sides.
Repeat once on the fabric and once on the stiffener.
Iron the stiffener to the wrong side of one of the pieces of fabric, matching raw edges.
On another sheet of paper trace a pattern that is about 1/4 of an inch bigger than your tablet on each side.
Cut out two pieces of cardboard from the second pattern.
On each piece of cardboard glue plenty of fiberfill to one side of it.
Pin the elastic diagonally at two corners along the same short side of the same piece of fabric and sew down.
Fold the piece of fabric in half and mark the center line. At these two corners that are on the same side of the fabric as the first two pieces of fabric, pin diagonally and sew down.
The closer the elastic gets to the center, the longer it needs to be. Lay your tablet on the fabric to help you place it. It will be used to hold the table in place.
Pin the fabric right sides together.
Do not sew yet.
Take the ribbon and cut in half.
Pin one piece of the ribbon to one of the short sides so that it is in between the two pieces of fabric and the edge of the ribbon is on the inside. (It should be centered along the short side.
Sew along both long sides and the short side with the ribbon using a 5/8 inch seam
Clip corners and turn right side out.
Stuff the first piece of cardboard into the opening so that it takes up half of the casing.
Now put the second one in in the same direction.
They should fill most of the casing
The open edge towards the inside and pin.
Attach the second piece of ribbon so a short amount is also on the inside and it is centered along the opening.
Sew 1/4 inch from the open edge.
Open the tablet cover and sew between the two cardboard pieces.
Close and glue the lace around the outside edge of the tablet case overlapping the edges
Once dry, put your tablet in, use and enjoy!
