both cotton and flannel!
Created especially to make a flannel cover for my cats bed...and she love's it. I'm not sure if it is technically a sage, pistaschio, pine or celadon...but these greens are pretty! (Ok, my favorite color is green.) If trying to match, order a swatch first. Also available in sienna rose tones. . Did you know this is a Matching Mug design? Some designs like this one have matching products in my other shops. https://www.zazzle.com/boho_leopard_green_coffee_mug-256166110082582656?rf=238898659040938075 . No time to sew?
