My grandmother used to make rugs. (wish I had a picture!) I saw one of her rugs recently that got the wheels in my head spinning. I came straight home and started cutting scrap fabric. The result was this:
Here's how to make your own. I used canvas for the back side of my rug. Cut canvas to desired size. You can serge the edges of the canvas or just turn them. I used a pencil to mark 1 inch lines all down the canvas.
Cut strips of fabric 1"x5". Fold the strips in half (short sides together) and press with fingers to make a crease to mark the middle. Overlap fabric pieces slightly with right side to canvas and sew them on the folded creases on to the marked lines. I place the fabric as I sew. I like to start from the middle of the rug and work my way out.
