Just my 2 cents worth: I'm working on a quilt for my grand daughter's graduation. Her favorite colors are red, green and turquoise. I wanted to use all those colors in her quilt. Since her favorite flower is a tulip, I decided to use red. I ordered red hand dyed and batik 4 and 5 inch charm squares for the petals, and turquoise ones for butterflies. When the fabric came, it was so beautiful, I debated with myself whether to wash or not. Okay....I bargained with myself....try just a couple with a tiny bit of dish soap. Thank GOD I did!!!!!. The red and turquoise batiks ran a lot....the hand dyed; not so much. My background is cream so if I hadn't washed them, I would have ruined the quilt that I have spent hours and hours appliquing. I know it is a lot of extra work but I will faithfully "test wash " the fabric before using it in a quilt that I am putting so much work and love into.
Good luck :wink:
