Finally was able to purchase India ink. Surprisingly, I got it from Michael's. Aaron Brother's doesn't carry it anymore. They are becoming less and less of an art store it seems.
The first drawing is of Ruby on a walk drawn from a photograph. She is a terrier mix and we believe the "mix" is part chihuahua. One can really see the chihuahua in this drawing. The second drawing is of Ruby tearing up her toy turtle. she's really going to town on it!
First drawing was done with pen and India ink. The second was done with a 0.9mm mechanical pencil.
