I was a bit surprised (and extremely pleased!) to find that the online Alabama Chanin store sells organic fabrics in addition to finished goods. To quote the web site: "the 100% organic cotton fabric is 60" wide, certified fiber grown in Texas, spun in Tennessee, knit in South Carolina, dyed in Mississippi and shipped from Alabama." For those who are serious about creating projects with these fabrics, swatch cards are available for $5.00 per card and offer 25 fabrics on each card.
Oh, and a visit to the site is mandatory, even if you're not currently in the market for organic fabrics. The look books are pure inspiration. The store sells 60" wide 100% organic cotton jersey dyed in true Indigo from plant and offers an entire look book using this fabric for inspiration.
And just in case you need reminding, here's a link to her wonderfully inspiring book: Alabama Stitch Book (PS - She sells kits for the projects from the book, too!)(PPS - all orders over $100 are 17% off until June 17th with code JUNE17)
