Making a shoulder bag that converts to a back pack

Still for sale:

First I have to mention that my Janome 1600P and Super Quilter frame have not sold yet.  I'll take the frame apart and bring everything downstairs next weekend.  In January I'll put it up on eBay.  It would have been nice to have a quilter try it before buying to make sure it suit their needs.  On eBay you take your chances.

The Bag:

Now on to the fun stuff.  I've been back in the sewing room!  This time I "shopped" from some boxes of fabric that were gifted to me.  Most of the fabric went to volunteer sewing but a few pieces were kept. 

This is a "prototype" and I made every mistake possible.  But it does convert from shoulder bag to a back pack.  And it matches two of my fall jackets.  So it will get used.  A larger one will be made using metal rings instead of fabric ones soon.  The metal rings will allow the fabric straps to pull through easier.  The cloth rings grab the straps making it a tad more difficult to switch from shoulder to pack.

Here's the finished shoulder bag:

This next photo shows how the straps are sewn so the bag can convert from shoulder bag to back pack.  Attach strap to bottom right, run through loop at top right, attach to top left.  Then attach a strap to bottom left loop, run through top left loop and attach to top right loop.  Like this:

To use as a back pack:  pull the straps that run along the side of the back out, so the portion of strap across the top come together to create the back pack.

The "prototype" bag has two pockets on front and back.  There are two pockets inside.  The top is enclosed with a zipper.

Now back to the sewing room to make one that is a bit bigger, with metal rings, and more zippered pockets to keep everything secure.
