It's a so adorable thing to see kittens play with their yarn!
I did this piece with graphite aquarelle from Faber-Castell,
it's a kind of water-soluble graphite pencil,
it comes with 6 pencils, one of each of HB, 2B, 4B, 6B and 8B.
The lead of the pencil is soft and very easy to work with water.
I did kittens first and then added their yarn with red water color after.
Little things in daily life are just beautiful! :)
