I've got some older books on miniature quilts - most are under 12 inches. Some used 1/8" seams. I made a couple and enjoyed doing it. I was using a Pfaff 1471 with the IDT.
The newer patterns that use Candies are fun. You can cut your scraps and experiment with a new technique or pattern without much cost. I've got the cutting dies for one and two inch squares and half-squares.
