Take 2 pieces of fabric a little longer and wider than you want your finished blanket to be because the weights fluff it up a little and make it end up a little smaller than you expect.
- How much weight? The formula I have seen used most often is 10% of body weight plus one pound. So my 35 pound daughter would need 3.5 pounds+1 pound = 4.5lb blanket
- If you want to be precise, figure out how many squares you will have and divide your finished blanket by that amount, so that each square has the same amount of weight.
- I learned the hard way that knit fabrics are MUCH harder for this kind of project. They tend to stretch and slide in any project but with the extra weight, it is a real trick to get lines even close to straight. I will be using wovens such as flannel from now on.
- I like the poly beads used in doll-making projects for the weight. I bought them at my local Joanns fabrics and I have seen them at Michaels crafts as well. I have heard of people using beans, rice, sand, pebbles, etc for weight, but I have heard various reasons that each is not recommended. Sand is not recommended because the silica can be bad for the lungs, rice and beans can mold over time and pebbles can poke through the fabric and be scratchy - the last thing an already sensitive child needs!
