I used a teal corduroy for the exterior and cotton polka dots for the lining. I added a snap and some pockets to the inside to make it a little more usable for me.
I must not have paid enough attention to the tutorial when it came to the purse strap, but if you make this bag, be sure to shorten it...it was too long for me. I just tied a knot in it for now, which actually works with this bag, I think. Maybe I'll fix it the right way, but this works for the time being.
I highly recommend making one of these bags...it's not as daunting as it looks. Enjoy!
