I must admit that I did approach rug-making a couple of times earlier. I made this one from a thick upholstery piece (shown under the coffee table).
And I managed to repurpose burlap coffee bean bags to make a couple of smaller rugs for our bedroom.
In both cases I liked the result and this time I used a coarse wool blanket to make a rug for my son's room. It looks like our pooch Gordy loves the way it came out, as well! It's pretty easy to make, especially for someone who knows how to quilt.
Besides the blanket you will need a piece of duck cloth, canvas or any other heavy-duty-type material for the backing. Due to the heavy fabric you use for the backing I wouldn't recommend to approach this project if you have a basic sewing machine with plastic parts inside. I had one of those and totally ruined it with a similar project. Please make sure that your machine can handle at least 3-4 layers of thicker fabrics.
You will need piece of a backing larger in size than a finished rug. Please account for at least 2" along each of the 4 side edges if you don't plan on using separate rug trim. Due to large size I usually lay out the backing on the floor. You can use clear wide or painter's tape to tape the fabric to the floor (to prevent it from moving).
If you use wool blanket you might want to wash and dry it on a high-temperature setting (that would bind wool fibers together making the blanket thicker). Cut the desired size and lay it on top of the backing piece.
Baste the top and backing together starting at the center towards the corners (the way you would do a quilt). I like basting along the edges, as well.
Stitch the trim using straight stitch along the edges and zig-zag setting at the corners.
Now iron-press along the edges and you are done!
