I mostly use 100% cotton small to tiny print calicos mostly in country colors. I like dark print on white to light background or light print on dark to med backgrounds. But am open to most anything as I am trying to expand my thinking. I am a miniaturist but have also done Doll Quilts and Wall hangings so can use larger prints just not huge prints. I like having resources to draw from when a whim hits. I'm not one to try to use up every scrap. I love to have scraps for when I want or need to forage for a particular color or print.
I have lots of cotton prints mostly small to tiny print but I also have stuff I have been given which is medium prints. I do have some batiks but it isn't my thing so dont' have alot of them. As far as I know all of mine are 100% cotton.
I can do down to 1" up to any size scraps.
