High-loft polyester/cotton-blend batting, full-size package
A comforter adds softness and a touch of color and texture to your bedroom and is often the centerpiece of your décor. Comforters can be expensive, however, and it can be difficult to find exactly what you want. Making your own comforter is a simple project that can be completed in just a few hours. With basic sewing supplies and your own creativity, you can create a one-of-a-kind comforter that reflects your style and makes a big visual impact in your bedroom.
Wash and dry your fabrics according to the manufacturer's directions. Iron all fabric carefully and trim off any threads from the edges.
Unfold your fabrics and lay them on a flat surface. Standard fabric is 44 inches wide, while home décor fabric is usually 54-60 inches wide. A standard full-size comforter is 80 inches wide by 90 inches long.
Cut two lengths of your main fabric so that each piece is 92 inches long -- which is a little bit more than 2 1/2 yards. Cut two lengths of your coordinating fabric so that each piece is 92 inches long.
Turn the main fabric pieces right side up and lay them side by side on the long edges. Arrange them so that, if they are patterned fabrics, they line up and the pattern lays smoothly. Pin the two long edges that are arranged together with the wrong sides together. Trim off the outside, unpinned long edges so that each piece is 41 inches wide. Repeat with the coordinating fabric.
Sew each long pinned edge with a straight seam and a ½-inch seam allowance. Press open the sewn seam on the main fabric and the coordinating fabric so the seam lays flat.
Lay the high-loft batting on a flat surface and unfold it, smoothing it out as you go. Place the main fabric right side up on top of the batting, and the coordinating fabric right side down on top of the main fabric. Pin all three layers of batting and fabric together on all four edges.
Starting at the middle of the top, sew around all four edges using a ½-inch seam allowance. Stop at each corner with your sewing needle down and lift up your presser foot. Turn the entire comforter 90 degrees and lower your presser foot. Keep sewing until you get back to the top of the comforter. Stop sewing about 6 inches before you started sewing to leave a turning opening in your comforter.
Trim off each corner edge at a 45-degree angle so that your corners will lay as flat as possible. Cut as close as possible to the corner seam without cutting through the threads.
Turn your comforter right side out through the 6-inch turning opening in the top of the comforter. Take your time so you don't rip the opening, and stop frequently to adjust the bulk of the layers so they are as smooth and flat as possible. Push out each corner individually.
Iron the front and the back of the comforter to remove wrinkles and encourage it to lay flat. Fold all layers of the turning opening ½-inch down into the body of the comforter so that the folded edges of the opening are even with the top sewn edge. Pin the turning opening closed.
Sew around all four outer edges of the comforter with a ¼-inch seam allowance and a straight seam, which will lock all the layers into place and prevent shifting of the fabric and batting and will close the pinned turning opening edge. Backstitch at both ends of your seam.
Shake your comforter out to fluff it up, and place it on your bed.
