Rainbow maker day 2 - card 1

Day 2 was all about rainbows stamping. For my first card I used Jennifer McGuire's technique of repeat stamping. By using just a few colours of ink but overlapping them, new shades were created. For example on this card I used red, then red + yellow, pure yellow and then yellow + green and so on.
The stamp set is a rather old one from Simon says stamp, from the November card kit 2014.
