Bored yet? I'm not... plus I tweaked how I made this one!
I boxed the corners as directed in Noodlehead's great tutorial (link)... but found it awkward marking the corners as well as sewing the corners together. Then I remembered that I knew another way to do this.... from my Fabric Storage Bin tutorial (link). This is what I did...
I dug in the trash by my sewing machine and pulled out a corner cut off an earlier bag and measured it... about 1.5" square. Then, using a specialty ruler, I marked all four corners.
Next, I cut out the marked corners and the bag looked like this:
Taking the bag to the sewing machine, I opened up a corner...
... and, matching the seams and the cut edges, pinned the opening together.
Then, I sewed the opening closed.
After I sewed all four corners, I turned the bag right-side out and went on to finish the bag as usual.
I made the pocket from a 4"x5" rectangle of fabric to make it a little smaller than the postage stamp bag I made previously. That pocket started with a 4"x6" rectangle. I like this size pocket better.
