I always do.this last one I am doing,I bought 108 inch fabric and three yards I knew I was takingit to a long armer and they like a little extra,and after washing it even though I took it out of the dryer immedaitley and folded it nicely it still got lots of wrinkles,and I hate to iron something that big.My solution you might ask? I took it to a dry cleaners and the pressed it for me,20 bucks but it was well worth it,I didn't have to do it!
