In Stitches...

Hi ya'll. I am planning on making the leather-handled shoulder bag form Amy Butler's In Stitches. I have searched my hometown for the leather needed, but I am going to have to go online . Not that I have a problem shopping online. :)

Have any of you made this bag, and if you used leather, where did you purchase it? I have used our great, glorious Leader Google, but I really have not found a site I feel I can trust yet. Any good sites you can lead me too? Or, if you didn't use the leather, how did you substitute?

Many thanks to you wonderfully crafty bloggers out there!
