I received an email this morning from Geta's Quilting Studio. ALL patterns are on sale for $5. And there are patterns for purses, bags and quilts. I have ordered from them many times and they are great to deal with.
Not affiliated just a happy customer!
BTW - they have a bag pattern that is a simpler version of the Quattro bag. And she gives you directions on how to enlarge and reduce the pattern to make multiple sizes. All of her patterns are very easy to follow.
