I think my favorites are the heavy duty ones, like these Bemis Sacks. I have several that are dated - most were used in the 1930s and 1940s. These are heavy, nubby, just a wonderful texture and will last another 80 years. I use them all around my house, inside and out - on wicker and my leather sofas too. I have some to share listed in my shop - thanks for stopping by and have a lovely weekend!!
