On my prior Catalina, I faced the same problem. I did as the others say and just cut the string that holds the button. I removed the covers and washed twice on gentle and air dried. It actually was not to difficult to re-install the covers...I did use some powder. I could not figure a way to get the buttons back on like the original ans was concerned that it would not look "right". My fabric was a loose weave and you could not see the remaining button hole....the covers looked so much better that it wouldn't have mattered amnyway.One other suggestion is to clean your foam...it removed the built up odors and made all the difference for the admiral. One way to do it is, fill up a kiddie pool with water and 1 gallon of bleach. Toss in a coule cushions and walk on them to completly saturate, let sit 10 minutes then remove, prop them up on something to drain and air dry for a couple days...Best of luck,Stephen
