Finally, the right type of linen :-)
I'm so happy! I've been searching for the right type of linen for the whitework tablecloth for almost a year, and finally I got it today :-)
I ordered it from naturtuche.de , and it's this type. As a basis for a whitework tablecloth, it's important that the linen has a thread count of about 18-20 threads per cm, so it's possible to do both counted stitches and "free" stitches. The cloth I ordered has about 19 threads per cm. For those of you who live in the Netherlands: this shop is incredibly cheap compared to Dutch shops. In the Netherlands, people will usually ask about 35 euro per meter for high quality linen, and only this costed 11 euro per meter. Do take a look at their wool too, they sent me some samples of it and it looks beautiful. I will use linen embroidery thread from the Mulberry Dyer.
It's strange that you can't find these materials in the Netherlands....
