This is what you will need to create the background:
Credit or Gift card
Heavy Paper (I use mixed media paper)
Place a bit of gesso on craft mat, using credit or gift card, pick up some gesso on end of card.
This next step is the tricky part but it's also the fun part! Holding the plastic card as flat to the paper as you can, lightly drag it down the length of the card stock. You don't want to have a solid covering of gesso so keeping the plastic card flat will aid with that. (I usually practice a bit before I use my expensive paper)
Allow to dry completely before next step.
Last step: have fun staining!!! I press my dauber onto the craft mat to get the stain flowing then I liberally add stain to the card stock. The gesso resists the stain giving you a fun unique background every time you use this technique! For a bit of a finish I used distress ink on the edges of the card stock.
For my finished card I used the sweet birds: Black Capped Chickadees Red Rubber Stamp and Happy Spring 2 Red Rubber Stamp for the sentiment. I also used Scallop Circle Nesting Die to frame the image.
