I have been taking apart a donated top. It was much too large for what we need so why not make a single and a throw? Good idea, until I tried to put some of the pieces back together. I swear that two different people worked on this top. One person measured the sashing and proceeded to apply it to piano key sections that were significantly longer--lots of bowing and ballooning. The other just slapped the sashing on and then cut--14 1/2 inch blocks sashed on 2 sides but the sashing ranged in lenght from 14 1/2 inches to 14 7/8 inches. Yes, the blocks were stretched out of shape. Had to dampen and gently manipulate them back to their proper size. Argh!!
This will be a pretty top--when it is put back together properly. I do sometimes wonder if it is worth the effort.
