I crocheted this rug using two old twin size flat sheets. It took pretty much all of the blue sheet and a good amount of the yellow sheet. The finished dimensions are about 20" x 30". I really like the look and feel of it. I'm pretty new to crochet, so I started with a basic rectangle, but I want to attempt an oval or circle next.
This is a picture of it in use in my kitchen, though I'm giving it to my mom and she'll likely put it in front of the vanity in their newly renovated bathroom, where it'll look much nicer:
This is a full shot of it:

Thanks for looking!
