Conductive Fabrics provide shielding

Here's just a sample of clothing that works for shielding when made of this silver/copper/nickel fabric. There is a more expensive 100% silver fabric which would also be good.
Double the fabric to two layers and this provides quite a good shielding. It doesn't take any sewing either or very little. Just double the fabric and make a blanket and this is really good shielding.
