The plan was to make a weighted blanket for our youngest son. That is what he really wanted. I found this really cute cat fleece. He is a big guy- 6'4" and 250 pounds. a weighted blanket should just be big enough so that all the weight is actually on the person. I figured I needed 12 rows across at about 5 inches and 14 rows long at about 5 inches. And since the entire weight should be 10% of body weight, his was 25 pounds. I worked hours on this. It is not easy to slug 25 pounds through the sewing machine without catching any poly beads under the needle. I did break 2 needles and dumped a bunch of beads on the floor.
