I have washed and pressed this fabric the same way as I washed the main fabric....the instructions on the fabric say to dry clean it but it has washed and pressed beautifully.....so I have this to cut out and mark, I will then sew the darts separately then put the two fabrics together and treat them as one.
This is the pattern I am using, I have used it a couple of times before to make tailored trousers. This pattern has been altered to fit me and I really like the fit of these trousers so I can just get straight on and make them without having to alter a pattern which takes me ages. Anyway these trousers are going to be more of a relaxed fit with no creases. I have straightened the ends, washed and pressed the fabric and line dried it, that is the way the trousers will be washed I won't put them in the drier.
I am making a pair of beige trousers for my next project. The fabric is a cotton and linen mix which I bought last year and never got round to making up. I know these are going to crease like mad but that is part and parcel of natural fibres. As you can see I have already cut the trousers out of the fashion fabric, this is the front you can see, I marked the crotch, knee and grain lines as well as marking the darts and the position of the fly front, I also marked the seam lines and waist line with tailor tacks.
