I used various patterns, none of which I completely liked, so I went my own direction.

I dug this beloved yellow fabric with florals of pink and blue from the stash that had been waiting for years go become something. I had enough to cut out both a backpack and a tote bag. First, the backpack.

Here are two views of the front, flap down and flap up.

I even inserted grommets from my stash. I threaded ribbon from my massive fabric stash. It's holding up rather well, but then I only use this lightly. Even so, when it wears out, I have other ribbon I can use.

And the back. I used metal clips from a much loved back pack that was worn out.

Now for the tote bags. The first was made with this lovely yellow and blue fabric from the stash. I had trouble with the handles, so once again I dug through my ribbon stash. I decided to use this blue taffeta ribbon. The original handle attempt was sewn inside, so the handles are beguilingly cushy.

For pockets, I have one on the outside (seen above) and one on the inside (seen below).

The second tote bag I sewed was with this lovely toile from the stash. It has an outer pocket (seen below).

Below you can see the inner pocket.

Tote bag number 3 is my piece de resistance! Note that this is the same fabric as the back pack, yellow with florals of pink and blue. This one has a zipper! Also an outer pocket on this side...

Oh, here's the bottom...

Side pockets...yes, on each side!

And the inside!

Finally the zipper cases from my smaller stashes of fabric. Remember this fabric? I had enough for a small bag.

For the inside I dug through my quilting stash...

This stash fabric was originally a retired home decor sample fabric from JoAnn. I think I paid a dollar for it. I just love it! I had enough for a larger size.

I dug through my quilting stash for something that seemed to coordinate well.

Then I found this in the stash. I had purchased it a couple of years ago at a quilt store for my daughter, while I was collecting Row by Row patterns. This was actually a pre-cut fat quarter size from one of the quilt shops.

While giving my daughter sewing lessons, I realized that she didn't have anything handy in which to store her tools, so I told her Merry Christmas! She loves the quilt fabric (again from my stash) that I chose for the lining.

I had enough fabric and supplies for one more zipper case, which I packaged in a baggie. Sometimes I only have moments of time to dig through the stash and cut things out. Then I package them in zip lock bags. Later when I have a chance to use the sewing machine, I grab a project that is ready to go.

So, the back pack has already made journeys to Harpers Ferry and Bears' Den Overlook.
The tote bags are many, but will coordinate well with various outfits when I'm out and about in a more leisurely manner than hiking.
I'm leaning towards using my zipper bags for various art implements as I delve into the world of en plein air. And not that I'm an artist. I'm a want to be artist...which means I don't know how far I will go with this...so I can't yet make up my mind! But I do think that while learning, I'll carry all of my journals and zipper bags of supplies in the yellow and berry tote bag that has a zipper and umpteen pockets!
