YOU CAN BUY MY BOAR FABRICS
Thanks to Spoonflower for making this possible!
The basic quilting weight cotton is $18 per yard.
I’ve only seen the fabrics printed on that, but there are other, fancier fabrics, too: upholstery weight cotton ($32/yd), organic cotton sateen ($27/yd), organic cotton knit ($27/yd) and bamboo/cotton rayon ($27/yd).
You can get a test swatch for $5 to see if it really is the right fabric for you.
