Efka78, Bippi, thank you both.
For me it was a relax, so I do not think it was too difficult... I was doing it step by step, stitch by stitch, and finally it was done. And I have realized, the bigger the chart is, the more relax I would have with it.
On the other hand, I think, that for beginners is more difficult to collect right colors, floss, canvas, maybe needle... Not alone stitching. If we have correct schema there should be no problem to stitch step by step. As this was kit, with floss of high quality, as well as canvas, I do not have any problem with it. Moreover I have understood from this first chart, and from another forums, how to start and now I am able to x-stitch whatever. Of course I am picky person, so I stitch only what I like, what I want and what I enjoy... :)
