Since TWO of my sisters are now pregnant, I am on a baby crafting train. I decided to make a diaper/wipes case, but it really could be used for anything. Give it a try...
To make the case you'll need:
(2) Front piece = 8 x 11 inches
(2) Back piece = 8 x 14 inches
Cut out a front piece in your outer fabric and your lining fabric. Cut a back piece in both as well. So you'll have a total of 4 pieces of fabric for one case.
Next, sew the front piece to the back piece, right sides together with 1/2 seam allowance. Notice the trimmed corners on the bottom. Repeat for the lining.
Sew a piece of velcro to the flap of the lining and also to the body of the outer shell.
This next part is a little tricky to explain. You place your front piece and your back piece together, with the right sides of the top flap together. Pin the two flaps together. Sew along the flap with a 1/2 seam allowance. Again, trim the corners. Next turn the outer shell right side out, making sure it's completely turned out. Then shove the the lining down into the outer fabric. It should look more like a case now. Fold down the fabric at the front opening and pin it into place. Iron and sew along the opening to the outer edge.
