I have just started using batiks. I like the way they work, but like all fabrics, I wash (rinse) all my fabrics before I start. I do like using them for backing on my baby quilts, but you really have to look around to find them in my local. Many stores will have a few bolts, but I am getting ready to start a quilt using 10 different fabrics and I thought I was going to poop out before I found all the colors I needed. I guess I'll start figureing the price of a tank of gas in the quilt cost!!!
