I was hoping to get some advice from y'all on printing a slipcover for my sofa. I already have the slipcover -- just an oatmeal colored duck fabric -- that has seen better days. What would be the best method for printing it? I would want it to still be washable. Should I use the contact paper method that is mentioned in the book (since this is a large piece)? If so, what would be the best way to apply the ink. Or is there another method that would be better? Thanks in advance for any help that you can offer!
