Showers Bring Flowers felted wool penny rug tablerunner by Cath's Pennies Design
This table runner design is for felted wool; but I am sure it would also work for cotton fabrics. You would just have to use a stabilizer like wonder under to give the table runner some stability.
I haven't tried this but I asked the designer about it and she seemed to think it would work.
Finished size: 11" x 26"
