I always add to my pattern (ex. if it say 1/2 yd I go to a yd) then I also have a couple on line sites for batiks that I love so I watch for them to go on sale and then stock up when the prices are better. Batiks Etc and Sew What Fabrics and Patsy Thompson have some pretty good prices on batiks (some starting at 6.75 per yd) I also got an email from Patsy Thompson designs this morning that she is offering 20% off everything this weekend
