As I showed some days ago
I immediately started stitching
on another black and white piece of felt.
This felt is not as even as the first piece,
because of the extra black pre-felt circles
I laid on top of the white wool tops.
(but that hasn't any influence on the stitching)
I didn't put any white pre-felt on the black wool :
the black fibres would migrate up through the white !
I now have a new tool for the patterns on the wool :
a pen with white acrylic ink.
It works very good
it is just visible and it rubs off easily.
For the white parts I still use the paper templates.
The name :
"Wheels of time"
