Down feathers provide a luxurious, soft stuffing for a variety of items, such as comforters, pillows and couch cushions. However, the soft down stuffing may also contain feathers that end in sharp quills. The quills can poke through fabric that is loosely woven, which is uncomfortable when sitting on a couch. Pulling the offending feathers out of the couch is a temporary solution, but this action eventually depletes the filling. Instead, keep the feathers contained with a few supplies.
Obtain a ticking fabric for a down-proof cover. The fabric should be tightly woven with thick thread. A tight weave prevents feather quills from poking through the fabric.
Unzip the cover on a seat cushion and pull out the down feather cushion insert. You may unpick the seam on one side of the cushion if it does not have a zipper. Measure the length and width of each side of the insert, such as the large flat panels and the narrow side panels. Add an allowance of 1-inch to each figure. Use the measurements to cut pieces from the ticking fabric.
Match the pieces and pin them together. Use the cushion insert as a guide so you can match them correctly. Hand-sew or machine-stitch the pieces. Ensure that you leave an allowance of a quarter inch for each seam. Leave one side open for the down feather cushion insert.
Stuff the cushion insert into the new ticking cover. Hand-stitch the open end of the cover closed. Place the form into the cushion cover and zip or sew it shut.
Repeat Steps 2 to 4 for the remaining seat cushions.
