Welcome to the Quilting Board!

The fabric I used was very badly wrinkled so I had to iron. Ironing it did not pose any difficulties later in the project. I would have had lots more had I NOT ironed it.
I always press and starch. I cannot cut or measure any fabric without all the wrinkles being removed first. I cannot sew the next seam if there is a wrinkle. Call me anal, but I don't like the movement of wrinkles that can cause seams to be even remotely wonky. Starch is one of your best friends when doing OBW, second only to using those straight pins. I also press the seams open, because the OBW I make are wall hangings, not quilts that will be used and washed.
What is OBW?
OBW stands for One Block Wonder. There is a list of the short hand terms here on QB-Quiltingboard. A OBW is a method of cutting a 60* triangle out of 6 repeats in the fabric that are matched and stacked one on top of the other. There are many fine examples in the Quilt Gallery section in Pictures.
I usually rip/tear my fabric into my repeats, and then starch and press each of my repeats before starting to cut.
