How can I change the old down coat to the back cushion?
Take down the old down and put the inside down into the bag you made. Remember that the middle process must be light, and if you're sensitive to feathers, you'd better wear a mask.
First, you can use the sewing machine or sewing thread to connect them until you cut the pattern you want. Remember to leave a mouth. We want to put the down plug in.
After the stuffed down, we can seal it. You can also sew a lovely coat for it. The warm soft cushion is finished.
