Used just inks in these pieces.  Started with Daler Rowney FW Inks and Liquitex Acrylic inks.....then used Amsterdam Acrylic Inks.  Found that the Liquitex seemed to spread and bloom more than the FW and Amsterdam.  Really loved working with these abstracts and playing with color combinations that had not tried before.  Such a great experience and class. Thank you Denise for your incredible teaching and explorations.
