I commonly go to the thrift store to get my cloth, mostly in the ladies department. I take my micrometer with be and look through the shirts mostly, sometimes the pants and dresses. I find every kind of cloth I need for patching and other projects made from cotton drill and pure linen in different thicknesses. All of these pieces have already been washed and wouldn't shrink any more. Many pieces of heavy pure linen make excellent linen bags and charcloth. Most times I only pay 99 cents to $2.99 for all the cloth I need. Look at the labels. If the label says rayon or other plastic based fabrics, they are passed by.
