How it works
A common starting point in sewing guides is about 10 percent of body weight. Multiply body weight by the share you choose, then divide by 100 to get the total fill.
Divide the total by the number of pockets to get the fill for each one. This is a starting point for sewing, not a medical measure, so use the maker's chart as well.
Worked example
For a body weight of 150 lb, at 10% of that, the blanket takes 15 lb of fill, about 20 oz in each of 12 pockets.
Questions
Is 10 percent always the right share?
No. It is a common starting point, and many people choose a little less or more. Pick a share that feels comfortable to you.
Who should check with a doctor first?
If you have breathing, heart or circulation concerns, or you are unsure, talk with a doctor before using a heavy blanket.
Why split the fill into pockets?
Even pockets spread the fill out, so the blanket hangs evenly and does not bunch in one spot.
