How to: sew a duvet or coverlet without a center seam
Here’s an illustrated step-by-step guide on how to make a duvet or bedspread for a bed of any size, so that you don’t end up with a goofy and unsightly seam right down the middle of the bed.
Almost every fabric, upholstery or otherwise, will not be wide enough to make it across the full width of even a twin sized comforter. (Blue represent a bolt of fabric.)
If you don’t want your duvet to end up with a seam smack dab in the middle of your bed, follow these steps:
Lay out your fabric (blue) and cut 1 piece (per side) the full length of the comforter you are covering or the full length of the bed (and then some) if you only intend to make a single sided bedspread. Usually this length measures about 75-80″ long.
Now cut another piece of fabric exactly the same length as the first and cut it in half, down the middle.
Take the half sized pieces and place them on either side of of the full size center piece, sew the pieces together. Depending on the bed size, you will need to trim the side pieces to the correct overall width you are looking for. Repeat these steps if you are making a duvet and need a front side and a back side that will be sewn together.
Your bed will now look professional and with a finished quality of a design specialist with every detail in mind.
