Amazon one click purchasing is dangerous. After reading this thread I decided to buy a
Yazzii CA 120 A Carry-All, Aqua. https://www.yazzii.com/shop/yazzii-carry-all-ca120/ I bought it on Amazon. Only color choice was aqua and it was $87 plus $6 shipping. It was $118 on Yazzii. It does fit my specific need perfectly. I camp for one month at a time in a van my husband has made into a camping van. I usually bring some hand work along with me. The carry-all has room for the hand work project plus 20 pockets for all my embroidery threads, beads and a place to store scissors etc. I will keep my hand project in this case and use it for everyday sewing too.
Interestingly enough this will be replacing an Annie professional tote I made.

I use that bag (made a bit bigger than the pattern) frequently for work and as a carry on bag for the plane. It is perfect for those functions. Has a place for my laptog/ an outside zipped pocket and water bottle holder and several pockets inside. It isn't really good for what I bought the Yazzii bag for. The tote was very challenging (for me) to make and took a long time. The materials were expensive but where else could I get a purple bag with purple turtle fabric as the lining?
I can't imagine trying to make an organizer with 20 pockets including zippers on many of them. I think that would take so many hours and frankly I'd rather quilt than sew that. By the time I paid for the materials, my time would be worth probably $2 an hour. Instead I would have stuck with the plastic sandwich bags I used to organize things if the bag had been too expensive.
