Welcome Sandy from Washington State!
My DH who designs and builds things all the time was about to order those plans and build me one. However, I found a Grace quilt frame within a few hours drive from us on craigslist (all time favorite place to purchase used items). When we looked at it he told me it was great and about the same price it would cost him to build me one.
Can't wait to see your photos and find out how it is for you to use once you get it. You must be very excited. :-D
