I just checked out the above site as our quilt guild has had a request to make some of these weighted blankets. Looking at this company's price list makes me think that I will recommend buying them rather than making them. These blankets are 4 layers of cotton and are a good size so the material to make even one would be expensive. By the time I purchased all the necessary fabric, thread and weights, I don't think that I would save enough to make it worth my while to try making these. I'd be reaching for my cheque book on this one.
