(Buy your white fabric wherever you buy your other fabric. Sometimes combining several whites on whites are beautiful too. If you have scraps combining is a great way to use them up. Some of the greatest quilters do that. You can never go wrong with a white on white background with scraps for your pieces - very vintage looking!!)
(That is a very nice quilt with white in it with your name.)
That quilt is my hand pieced hand quilted Dear Jane quilt - I used Kona Cotton Cream for the background pieces - thank you for the compliment!
