I used method B. I started putting them in a shoe box and when it was full I had enough for the two quilts shown.
The stripped quilt is double bed sized. I found the lilac print and the pink in my stash. I used white on white prints for the white.
I used the leftover blocks to make the smaller quilt. Its about 55 x 66 inches. I didnt put the outer border on at first, but it felt unfinished. Adding the darker boarder framed it and it looks better.
