I am making a dress out of velveteen. The bodice was supposed to be lined with taffeta, but that was too stiff and did not fit properly. When I tried to make adjustments, pinned and sewn with the taffeta lining they showed on the finished side. Any ideas of how to get rid of the marks. The marks are right at the bust where they will show the most. The pattern is for a child who does not live near me and it is difficult to fit her. I am most concerned about getting the marks out of the velveteen. Any and all ideas welcome. Thanks.
