I have just got the material for the HAED Queen of hearts, and I bought 25c Lugana.
Could you please tell me if I have to stitch over one or two threats with one strand?
The count is very small and I am a bit puzzled!
Never did a small count like this before.

It is supposed to be over 1, if you want to follow the chart recommendation. BUT by no means does that mean you have to do it like that. I'd do a few test stitches in the corner before you start, just to make sure you want to go ahead. If you think its going to be too small for you then don't worry, your not alone. There are plenty of people who stitch HAED charts on 22, 20, 18, 16 count etc. I don't know if anyone ever stitched 2 over 2 on 25 count, but that might also be worth trying as well.
Have you been over to the HAED Bulletin Board? There are lots of people with much more advice and experience to offer there. It's certainly worth a browse of the WIP and Finished project forums.
HTH

Thanks Ruth for the advise, will have a browse on the HAED website and explore some more.
