You have a perfectly good futon that you would like to use as an extra couch and bed. The only problem is the cover on the mattress is stained, torn, or just hopelessly out of date. With some material and a few simple sewing techniques, you can bring that futon out of hiding and back into circulation. And, if someone wants to think you've bought a new one, let him or her. Only you need to know otherwise. Read on to learn how to make a futon cover.
Take your mattress off of the futon, and lay it in the middle of the floor. Make sure you can get to all four sides of the mattress.
Using your measuring tape, measure the length of the mattress first. Record your figures.
Measure the width of the mattress next. Record your figures.
Now, measure the height (or thickness, as it is known as) of the mattress.
Convert your measurements from inches to yards. Remember that 36 inches equals one yard.
Using your converted measurements, purchase the amount of fabric you will need, as well as the needles and thread, and the fasteners you have decided to use for the project.
Wash the fabric before you begin sewing. This will "set" the colors, as well as prevent the completed cover from shrinking. Make sure you follow correct washing procedures for the type of fabric you are using. Allow the fabric to dry thoroughly.
Lay the fabric out on the floor (design down—if it has a design). You may wish to put a sheet, blanket or other type of protection down first. Smooth it out, and make sure it is lying completely flat.
Put the futon mattress on top of the fabric, making sure all four sides are an equal distance from the edges of the fabric. Use your measuring tape to be certain.
Fold the fabric over, and pin or tape it to the mattress. Don't be stingy with the pins or tape, because you will be flipping the mattress over to check for fit.
Fold the fabric over the corners, and pin or tape the folds securely. You will want the corners to remain fastened together when you remove the fabric to sew it and attach the fasteners.
Flip the mattress over; make sure the material is stretched tight enough to eliminate any bagging, sagging or wrinkling, but not so tight that the fasteners will not hold when the futon is in its upright position. If necessary, flex the mattress a few times, and make any adjustments that may be necessary.
Once you are satisfied with the fit, flip the mattress back over, and mark the places where the fasteners will be attached. See Tips section for more information.
Remove the cover, and either hand-sew or machine-stitch the corner folds. Remember to leave a "pocket" so that the corners of the cover can be fitted over the corners of the mattress. Also, if you are using elastic banding around the edge of the fabric, now is the time to insert that into the cover.
Attach your fasteners, using your marks as the guides for placement. Follow any instructions that come with the type of fasteners you are using.
Put your completed cover on the mattress, put the mattress back on the futon frame, and enjoy your "new" futon.
