Wow! You've given me the inspiration to get going on my long postponed project. i almost left it for a professional since i had picked up some great indoor/outdoor fabric on the cheap (54 yds for $35!). I called a local woman about reupholstering a sofa and love seat that didn't need anything but recovering. Was quoted $1500 plus fabric. When I said I had the fabric she said there would be a $15/yd cutting fee. So back to the slipcover plan! I hope I have as much success as you did. Wish me luck!
I'm sure you will. Just take your time and study the structure of the sofa and love seat and you'll be fine. Don't forget to post a pic when you finish.
