By the way, to draw the image to the canvas I used a special marker that should disappear after about two days, depends on the kind of the fabric. I had to laugh finding out that it disappeared in quarter an hour - I didn't even manage to draw the whole picture! :-D
And this is in the evening. I tried to make a photo without flash to maintain the colours. I feel like a hero cause I was able to make one good picture in about fifteen bad :-D
I didn't think the colours of the fabric and the cotton would be so similar! But what can I do now..
I'm quite pleased I used the split stitch, with some stitches (e.g. chain stitch that would be faster) I have a problem making curves and acute angles.
