Depending on what type of silk it is, it can be very hard to work with. Charmeuse is a nightmare. It slips and slides and is hard to iron without leaving marks. Silk noil and some of the cotton like silks are pretty easy. Lightweight silks can be hard also.
With wearables and garment making, I had exposure to a lot of silks. They're beautiful and feel wonderful, but not always easy to work with.
