It's not a small project by any means, and it's pricey to make. The only real problem I had with it (besides turning it inside out and right side out, that was hard!) is the piping, I just don't do enough of that to be really proficient, but I finally got it the way it needed to be. It's kind of hard to wrestle the panels under the zipper foot when you have no flexibility or give, because of the stiffness from the Timtex. That said- I love this bag! I finished the outside of it yesterday, just have to press it and today I'm making the lining and adding a zippered pocket to that. It's a really nice size and I plan to make another one in a more spring/summer combo at some time in the future, so you know I wasn't TOO traumatized by the stupid piping. lolol

I'm using a geometric fabric, not Amy Butler's. It's black with orange/red/olive/peach squares all over it, it's by Blank Textiles. The lining is black with those same colored dots on it, dime-sized dots. DH has the camera or I'd show you. Because it's not the weight fabric that is recommended, I reinforced it with an iron-on stabilizer on all the exterior pieces except for the piping.

Bag looks great, though. And once you're that far, you don't want to scrimp on anything to make it less than "perfect".

These photos wash the bag out a little, the colors are richer and deeper, the black is more prominant than it looks here. Stupid flash! lol

I added the zippered pocket to the lining, it was so easy to do.

I was working in a rush since I'm flying to CO on Friday and have to work and clean the house before I can go. I wish I had had more leisure time to work on it, but I didn't. Next time I'll make one when there's no pressure. You can do this! I'll tell you one thing, though- I started out using my White machine and quickly switched to using the Bernina. It's more powerful and I didn't break a single needle. Having an adjustable needle (left, center, right) was crucial when it came to piping.
