Just as I was thinking of making a slipcover for my «sofa» chair... Thanks for this post, it was enlightening! (theinspiredroom.net)
I have made slipcovers with dropcloths and the fabric once washed and bleached turns out to be just the best! (atthepicketfence.com)
Our sofas came with their slipcovers, but I'm sure you could find someone who makes slipcovers locally if you checked with a fabric store in your area. (theletteredcottage.net)
