Yes but no longer the small cut pieces. I iron and starch the material before cutting. Not always but frequently. I avoid ironing, starching and steaming cut pieces as it causes distortion. To starch lay out the large piece of material, spray lightly with starch, maybe a bit more on creases, let it sit and let starch dry if it got a little too wet, and gently press iron. Do not push and pull the iron around too much. It is more a lift and press motion.
When I sew pieces together I either finger press or gently press but not iron to set the seam and press it to one side.
