Thanks everyone. It sounds like it's a personal choice. I guess I'll remove the paper before I put it together..... I'll press and trim to size. All your suggestions were great.
And I love that fold back method to paper piece. I'll have to try that on the next project. The only thing I wonder about is if you can put freezer paper in the printer. I don't think I want to hand trace all the paper piece patterns. The kimono block has 4 separate parts that get sewn together at the end. That would be 80 pieces of pattern to trace..... too much. I did hear someone say that they bought freezer paper in a regular 8 1/2 x 9" sheet size. Have any of you seen this?
