fabric of choice
Measure the size of whatever it is you're making a case for. Mine for example was for business cards.
Take the height of the business cards, add 1/2'' and multiply by two to get the height of your rectangle. As for the width, use the length of your card plus 1/2''.
Then for the envelope shape, add a triangle to the top of your rectangle about the height of your card. Allow yourself 1/2'' for seams all around. After you've figured out your numbers, draw your shape twice so you have two pieces of fabric.
Cut the shapes out and sew together, right sides in. Make sure you leave room at the bottom for you to be able to turn it right side out. Flip and press.
Fold like an envelope, press again and sew the side edges. I wanted to add a bit more color to my new little business card case so I added a colorful button I had on hand. That's it!
I've already had a request for one from a friend. Happy crafting!!
