My favourite piece is Clearing by Ana-Maria Rugescu. I agree with you that, to create this kind of art, one needs to be very meticulous. All good art inspires, and in relation to this one, I know you had a good dose of inspiration since you enjoy sewing so much. The art of fabric patchwork has always caught my attention. And well… yes, some materials are more challenging than others, whether because of their delicacy or their hardness.
Cheers!
