if you collect your cattails and then hang them up to dry for a week before you use them they will pre-shrink. Then when you're ready to use them, soak them so they are playable again and then make your weave. they won't shrink anymore and your mat will stay tighter. 😊
Thank you! I'm a therian, and I'm making an outdoor den. I want pillows and a mat to sit on, but I want to leave as little from indoors as I can outside
