American Girl, I'm tired and on my way to bed, but I think I'd try BFC-Creations.com. I know they have a lot of purses, even purses where you make one "inside" part, and it can be put into a lot of different "outside" parts. I don't mean sewn in, but interchangable, like you could pick the inside with all your stuff right out and put it into another color outside, presto, new purse! That kind of thing. I thought I remembered some clutches there, too, but I'm not certain of that. It's a great site, anyway. Good luck to you, and hugs, Marji

Here I have some links to free sewing pattern sites.
There are many more to find when you just google "clutch purse free pattern" and switch to the picture tab- so you will see immediately if you like the purse at all.
