How to fix a person to a chair

You can prepare a rope

and then fix your hands on the chair backwards.

Then visually check the approximate length of the straps needed, and cut the fabric into long strips. You should cut out 5 strips at a time. Then fold the cut strip of fabric in half to create a crease in the middle. Then fold the two sides inside, and then fold the folded strips of fabric together. Take out the needle and thread and sew the folded strips of fabric together, and do the same with the other three strips. Cut the remaining strip of fabric into 4 pieces and sew them together in the same way. Next, take out the seat cushion, determine the position of the seat cushion, fold the two ends of the short cloth strip into a ring, and sew it at the corner of the seat cushion. Then, after fixing a few stitches with a needle and thread, place the sewn long strips of fabric on top of the short strips of fabric and sew them together. Then sew the strips of fabric on. After all the fabric strips are sewn, the cushion straps are also sewn. Then just place the cushion on the chair, thread the long strap along the chair legs, then thread it into the loop strap, and tie a slipknot to secure the cushion.
