Filigree carpet

I (painfully) advance on my filigree composition.

I must have done about half of it, in 15 hours...
I may have seen a little big, or I may be filling in a little small :-D

And as one has to warm up when taking the pen, I do little things each time before continuing on the big composition.

For example, a flower design that I invented a few years ago but that I'm never tired of reproducing.
