So here are three backgrounds I've made using, basically, just ink, Queen Kat Designs stamps and cardstock.
This was just super easy to do. I used my cat's eye ink pad to "draw the circles. A little hippie love with Queen Kat Designs' Girlfriends Stamp. I colored in my stamped image with markers.
The square colors of ink should be very familiar to you. I just pressed my square ink pads and made a simple multi-colored background for my QKD Girlfriends Stamp. I also used the perfect sentiment from QKD's Friends Forever Stamp Set.
Hope this inspired you to have fun with your QKD stamps as well as make your own cool, funky backgrounds. Have an inky day!
