Polyurethane foam gives a low-cost alternative to more expensive high-density cushion options. The open-cell foam is durable and comes in a variety of thicknesses, which means you can use it to substitute a loftier sofa cushion or to earn a thin chair cushion. Cutting the foam and creating a custom-fit cover does not need exceptional tools. With a thicker upholstery fabric makes for a stronger cover which also protects the cushion, but you can use fabric that is thinner if heavy wear is not a concern.
Mark the desired size and shape of the cushion on the polyurethane foam sheet. So the cushion has a sleek, even border, cut along the line using a sharp knife, which makes a cut.
Assess height, width and the thickness of the cushion. Insert the height and one inch to the width dimension. The thickness measurement and insert double the height dimension plus one inch into the doubled thickness, so the dimension is enough to pay the top and bottom of the cushion with a peice of fabric.
Measure and mark the side of the fabric utilizing the adjusted span and width dimensions. Cut out the fabric along the lines that are marked.
Fold the fabric in half lengthwise with the sides together. Sew a seam along the two shorter open sides, from the fold to the conclusion of the side.
Fold both sewn corners in diagonally on every corner of this cushion’s closed end to former a miter, with the fold the same length as the height of this polyurethane cushion. Sew along the miter fold and then trim off the extra fabric from the corners. The corners move on the front of the cushion.
Sew a hem around the raw edge of the end of this cover, folding back the fabric.
Slide the cushion into the cover. Fold in the sides, very similar to wrapping a present, so they overlap and the top and bottom flaps fold . Cut a length of tape to exactly the same span as the top and bottom flaps. Pin the hook section of the tape into the outside of the bottom flap, and pin down the loop portion into the inside of the flap.
Remove in the cover and then sew the hook-and-loop tape into the cover. Place the cushion back in the cover with the back of the pillow in the end of this cover, and shut the tape being used by it.
