I just finished sewing up a journal clutch/cover using Keyka Lou's pattern (she's on etsy, NAYY).
It was a quick and very satisfying project to make. It fits the pocket sized Moleskine journal perfectly with a little room to spare on top to fit a pen. There's something very pleasing about the Moleskine journal and to have a nice little cover just enhances it .
I'm working on a second one right now and I would like to have some padding in it, so I might use some batting, or maybe wait to go buy some thicker fusible fleece. I used a thin fusible fleece on the lining and a medium sew-in interfacing for the focus fabric. I didn't quite get the feel that I wanted which is why I want to try some batting or heavier fleece next time. Still love it though.
I reviewed this pattern on http://sewing.patternreview.com/cgi-bin/readreview.pl?readreview=1&reviewnum=41241 if you're interested in knowing more.
