This is the simplest & fastest method for sewing a cushion cover. In fact typical sized cushions can be completed in about 30 minutes each. The Box Corner Cushion utilizes one panel of fabric to make an entire cushion (unless it is a rather large cushion). No boxing, no zipper plaque, no top or bottom plates just one panel of fabric. This 30 minute cushion will include a zippered opening on the back side to accommodate the insertion of the cushion's foam. It is also a flippable cushion, meaning both sides can be used as the decorative side.
Use the Sailrite Fabric Calculator to get instant cut measurements for your size cushion so you can quickly produce a cushion without doing complicated math. Sailrite's Fabric Calculator is designed to produce a cushion cover that is tight fitting over the foam (slightly smaller than the foam) for a simply gorgeous cushion.
