I found this vinyl cube ottoman on clearance at Target a few years ago. I knew it wouldn't go with my decor, but liked the shape. So, I picked it up and decided to find some fabric to cover it.
I ended up cutting up a quilt (gasp!) that I got from TJ Maxx. They always have a nice selection of throw quilts for less than $20. My mom used a quilt to make stockings for me and my three sisters this year for Christmas, and they turned out adorable!
I simply cut a square for the top and cut more squares for the sides. "Sew" simple!
