The pattern is pretty straight forward, so I think it would be fine as a first purse project. I suggest reading through the directions once or twice before starting to get a feel for what you will be doing. I use a walking foot, it helps with the bulk. I also make my handles a couple of inches longer, which requires an extra strip of fabric and fleece. I tend to work assembly line style. I fuse all the fleece on, do all the quilting and prepare the handles. If I make another for myself, I'll add a snap rather than the button/loop.
I made myself the mini one, and it's still big for me as an every day purse. If it weren't for the glasses, I would have stuck with my cell phone wallet! LOL I've made several, sold 3 so far. They are very pretty!
