I used fabric scraps from my studio and embellished the business card case with some ribbon. I love Amy's fabric, but I'm not as big of a fan of her patterns. This one called from some heavy interfacing, that I didn't have, and I manged to put the substitute in the wrong place. The folds in the case were very bulky, and my finished case buckled out a lot. Though, since I've been toting it around, it has flattened out.
The great things is that it still holds my business cards, so I'm happy!
