I have a bunch of panels to make animal-shaped pillows. . .these were bought with a bagfull of fabrics, so I don't have any idea as to the age of them.
I'm going to guess (based on my fingers!) that they are cotton/poly blends. . .there are eight of the one size and the cat one is quite large. I put a magazine in the picture on the left hand size, for scale. Each has the back pattern on the other part of the panel.
They kind of smell like a cedar chest (which, if old fabrics are going to have a smell, isn't too bad!)
If you're interested, please let me know what you'd like to trade for them! Thanks!
