I don't normally sew polyester fabric because I find it difficult to handle...it can be so slippery, not to mention the static cling factor - ouch! I prefer natural fabrics, i.e., cotton, linen, wool, but I promised myself to try new things this year and practice, practice, practice. I went to JoAnn's Fabrics and purchased two pieces - one a drab olive color crinkly polyester, the other a deep, rich navy/black textured polyester. Crazy! I'm working on the olive green piece this week, using Christine Jonson's Straight Shirt Jacket #723 for the pattern. It's a simple pattern, easy to sew, but the polyester fabric has a mind of its own. I think I'm winning the battle, but the proof will be in the finished garment. We'll see.
