If the puddle pad gets wet, pat dry with a cloth and then air out between uses. Hand wash or machine wash on a cool wool cycle. Hang to dry. Never wash on hot or tumble dry as this is likely to result in felting the item and leading to shrinkage.
Unfortunately the new wool puddle pads are currently not available while I am waiting on delivery of more fabric. Please email me if you would like to be advised when they are again in stock.
