Actually, there seems to be some cotton in this fabric. When cotton is added to a linen, it can add a lot of positive features. You still get the linen look, which is beautiful ...but you also get less wrinkling and less "stretchiness." Most of us know how it is when wearing a linen suit; you have to be careful how you buckle your safety belt in the car so as not to have that big mass of crinkling at your waist.
Adding cotton to a fabric also makes ironing and pressing easier. We washed this fabric before creating the slipcover and there wasn't a wrinkle in site! In fact, this hasn't been pressed at all.
On a side note: The chair is sitting on a device we think is very handy. It is a rolling pneumatic lift that has a plywood platform mounted to the top (you can see the silver handle on the far side.) We can raise and lower a chair to the appropriate height to prevent back strain. What a handy dandy thing this has turned out to be for us! We always love the creative part of what we do, but want to make the actual manufacturing process as smooth and painfree as possible.
