Really, really good ID case sewing tutorial with clear vinyl window. I just made one and it went really quickly. I bet I could make a divider inside with no problem whatsoever. I might alter the pattern to add interfacing to all of the exterior pieces (the pattern only calls for interfacing on the ID card pocket), otherwise I am absolutely in love with this pattern.
Tutorial for making a fabric envelope for safe carry of papers, etc. I need this for all the important things that get bruised and battered rattling around in my purse! One addition I might try; using 2 square pieces of the main fabric, unpatterned sides together, with a sturdy piece of cardboard sewn between them (as big as the center of the envelope, to make the whole thing more sturdy).
