I’m working on a coat from a Burda pattern using some inexpensive wool and am trying to underline with a cotton batiste as per Sandra Betzina’s recommendation. (this coat is an experiment. I’m going to make one for my sister in a beautiful cashmere/wool I bought from candelightvalleyfabrics. com) I’m having a hard time, though, getting the batiste to line up with the fashion fabric even though I was very careful in cutting it out exactly the same way I cut the wool. Does anyone have any suggestions? Also, how do keep the underlining from slipping while you work with it and the fashion fabric as one piece? I tried to baste inside the seamline with long running stitches but it seems to just make everything pucker. What am I doing wrong? I’m a pretty experienced sewer and haven’t had this problem with underlining before. Also, does anyone out there prefer using a rotary cutter to scissors – do you get a better straight cut with a rotary? Thanks.
