I've recently switched from using a spiral bound visual diary to one from 
Moleskine.  While I like the paper in the Moleskine  diary better, I miss being able to put my pen in the spiral binding of my old visual diary.  And I am pretty much over searching for my pen.  So, I decided to make a pocket for my Moleskine visual diary that had room for a pen as well.
This is a textile collage that my friend 
Lisa Walton of 
Dyed and Gone to Heaven gave me a while back.  I used it in a faux felt demo I did at the SCQuilters Retreat in Perth.  Actually, just half of it.

Looks like it will be big enough ... Houston, we have lift off!

I trimmed up the textile collage and folded it in half.  One more check on the size ...

... perfect.  Now which thread to use?  This is why you need a nice stash of threads ... dark orange rayon ... bright orange rayon ... a very rich orange cotton ... decisions, decisions, decisions ...

I think the dark orange rayon will do the trick.
First step was to stitch across the top of the pocket.  I used a wide zig zag and caught two strands of pearle cotton under the stitch.  I think that it makes for a nicer edge and maybe makes the edge a bit less likely to stretch over time.  Then I did 4-6 more zig zags across the edge, a bit narrower this time, to fill it in and be sure that the edge was well covered.

Here's a close up of one of the corners.  You can see the pearle cotton caught under the stitching.

And here's the back.  Yes, I used a bright pink cotton in the bobbin.  Trying to decide if the pocket needs to be lined.  Nope.  Looks OK as is to me.

To finish making the pocket, I switched from the open toed embroidery foot to a walking foot, reduced the pressure on the presser foot from 3 to 2 (we're sewing through quite a few layers here).  I stitched down the side 1/4" from the edge back and forth a couple of times, going slow enough to hit the same line of stitching each pass.  I did the same thing across the bottom.
Then I zig zagged the raw edges ... remember, no lining ... to keep things inside nice and tidy.  I didn't zig zag around the corner but stopped before I got there.

Here's a close-up of the top of the pocket ... notice that I stopped the zig zag before I got to the stitching at the top edge.

I cut the notch off the corner to reduce the bulk when the pocket is turned right-side out.  Here's a close-up of the corner.

And, just for completeness, a close-up of the corner on the folded side.

This took some determination.  Two layers of felt in the middle makes it sturdy but a bit resistant to being turned right-side out.

I used a chopstick to get the corner with the notch cut into it to look like a sort of square corner.
Another size check ... I can't help myself ... it's an Engineer Thing.

And here's the finished visual diary pocket.

Very good job, if I do say so myself.  Now, what to do with the other half of the textile collage?
