So glad you asked this question. I came across a "blanket" while cleaning out some drawers recently. It appears to be either an army type blanket or perhaps a movers throw. Pretty sure it is wool but will check that out first. I was thinking about cutting several pieces and stacking them together to get better thickness then washing and sewing the edges together or needle felting them together. Watson, I too am pretty cheap and those wool pressing pads are fairly expensive; plus I love to recycle things if possible. And yes, we used to have horses so I know what you mean ... feed, hoof trimming, shoes, annuals, shots, floating teeth, ... it just goes on and on but they are beautiful animals! I see that in your avatar and in your mosaic.
