I did a fair amount of sewing over the new year's long weekend.
Found this pattern online: http://www.museofthemorning.com/museblog/2013/make-a-big-beautiful-beach-bag-tutorial/
And made it out of some heavy cotton that used to be curtains in my last apartment:
Enjoy! The pattern is pretty quick and easy, and makes a nice bag.
Here's another picture, with the bag stuffed with THREE of my jackets! It's HUGE. I love it.
