I like both scrappy and planned quilts. But, the scrappy draws me because I am of a frugal mindset and like to use every tiny little scrap for something. Also, I find that while I am working on these, they do not look like much ... but when finished and quilted, people like them better than the planned ones. They go through and pick out their favorite pieces and talk about them and touch them.
I made a rail fence with 1930's scraps and there was one piece of Dick and Jane that had the word "go" on it. I was going to leave it out, but needed one more piece and had to put it in. The lady that the quilt was given to would turn it around and around until she found that piece every time. It was funny to me that I had nearly not put that in.
Scrap quilts seem to have a comforting factor to some ... like mac and cheese to kids or something. How strange that sounds ... but it is true.
Nearly all of my scrap quilts are for elders, sick, children, soldiers, etc. The custom made quilts (unless done from a deceased's clothing) are usually a planned arrangement.
Something to be said for both ways.
